The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.94 m on each side?

Answers

Answer 1

Answer:

8721.132 Kg.

Explanation:

The following data were obtained from the question:

Density (D) of silver = 10.5 g/cm³

Length (L) of silver = 0.94 m

Mass (m) of silver =.?

Next, we shall determine the volume of silver. This can be obtained as follow:

Volume = Length × Length × Length

Volume = L × L × L

Volume = L³

Length (L) of silver = 0.94 m

Volume (V) of silver =?

Volume (V) of silver = 0.94³

Volume (V) of silver = 0.830584 m³

Next, we shall convert 0.830584 m³ to cm³. This can be obtained as follow:

1 m³ = 1×10⁶ cm³

Therefore,

0.830584 m³ = 0.830584 m³ / 1 m³ × 1×10⁶ cm³

0.830584 m³ = 830584 cm³

Therefore, 0.830584 m³ is equivalent 830584 cm³.

Thus, the volume of the silver is 830584 cm³.

Next, we shall determine the mass of the silver. This can be obtained as follow:

Density (D) of silver = 10.5 g/cm³

Volume of the silver = 830584 cm³.

Mass of silver =.?

Density = mass /

10.5 = mass of silver /830584

Cross multiply

Mass of silver = 10.5 × 830584

Mass of silver = 8721132 g

Finally, we shall convert the mass of silver, 8721132 g to kilogram (kg). This can be obtained as follow:

1000 g = 1 Kg

Therefore,

8721132 g = 8721132 g / 1000 g × 1 Kg

8721132 g = 8721.132 Kg

Therefore, the mass of each cube of silver is 8721.132 Kg

Consider the following balanced equation:3Ca(NO3)2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaNO3(aq)If 24.2 moles of Na3PO4(aq) reacts with an excess of Ca(NO3)2(aq) to produce 50.6 moles of NaNO3(aq), what is the percent yield of the reaction?

Answers

Answer:

69.7% is percent yield

Explanation:

Based on the reaction:

3Ca(NO3)2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaNO3(aq)

2 moles of Na3PO4 react producing 6 moles of NaNO3.

As 24.2 moles of Na3PO4 react, theoretical moles of NaNO3 produced are:

24.2 moles Na3PO4 * (6 moles NaNO3 / 2 moles Na3PO4) =

72.6 moles of NaNO3

As there are produced 50.6 moles of NaNO3, percent yield is:

50.6 moles NaNO3 / 72.6 moles NaNO3 =

69.7% is percent yield

Which of the following isotopes are NMR inactive?
a. 1H
b. 12C
c. 15N
d. 16o
e. 19F
f. 31P

Answers

Answer:

12C and 16O

Explanation:

Here, we want to select which of the options are NMR inactive. For an isotope to be NMR inactive, then the net nuclear spin is zero.

What this means is that the number of proton present coupled with the number of neutrons are an even number pair.

What we are saying here is that the number of protons is an even number while the number of neutrons too is an even number. So the net nuclear spin in this case is zero.

in the case of oxygen, we have 8 protons and 8 neutrons. This makes the nuclear spin zero and consequently makes the isotope NMR inactive.

Same is in the case of carbon. There are 6 protons and 6 neutrons and this also makes nuclear spin zero .

In all the other isotopes in the question, we have odd number even number or even number odd number pairs of protons and neutrons.

A running track measures 1056 ft per lap. To run 15.0 km, how many laps should you run?

Answers

Answer:

46.6 laps

Explanation:

Step 1: Given data

Length of the lap (l): 1056 ftTotal distance to be run (d): 15.0 km

Step 2: Convert "l" to km

We will use the conversion factor 1 km = 3280.84 ft.

1056 ft × (1 km / 3280.84 ft) = 0.3219 km

Step 3: Calculate the number of laps that you should run

We will use the following expression.

laps = d/l

laps = 15.0 km/(0.3219 km/lap)

laps = 46.6 laps

The average atomic mass of the element T is 12.012 amu.

What is average atomic mass?

The average atomic mass is defined as the atoms' weighted average mass in a naturally occurring sample of the element.

It is also defined as the average atomic mass of all naturally occurring isotopes of all elements.

The average atomic mass  can be expressed as

Average atomic mass = f1m1 + f2m2 + f3m3

                                    = 0.989 x 12 + 0.01 x 13 + 0.001 x 14

                                    = 11.868 + 0.13 + 0.014

                                    = 12.012 amu

Thus, the average atomic mass of the element T is 12.012 amu.

CH3OH/H2O CH3CH2OH/H2O Both solutions have the same freezing point. (b) 20.0 g of H2O in 1.00 kg of CH3OH or 20.0 g of CH3CH2OH in 1.00 kg of CH3OH? H2O/CH3OH CH3CH2OH/CH3OH Both solutions have the same freezing point.

Answers

Answer:

See explanation

Explanation:

(a)

From the data provided;

Mass of methanol =11.0 g

Mass of solvent (H2O) =100 g = 0.1 kg

Molar mass of CH3OH =32.04 g/mol

Number of moles of solute = 0.343 mol

molality(m) of methanol = 3.43 m

Also,

Mass of ethanol =22.0 g

Mass of solvent (H2O) =200 g = 0.2 kg

Molar mass of C2H5OH =46.068 g/mol

Number of moles of solute = 0.477 mol

molality(m) of ethanol= 2.38 m

The greater the concentration of a solution, the higher the freezing point of solvent will be depressed. Therefore, higher molality, leader to a greater decrease of the freezing point.

Therefore, the freezing point of methanol CH3OH/H2O is lower than the freezing point of ethanol.

b)

Mass of solvent = 1 kg

Mass of water = 20g or 0.02 Kg

Molar mass of water = 18 gmol-1

Number of moles of solute = 20g/18 gmol-1 = 1.11 moles

Molality= 1.11 moles/1 kg = 1.11 m

Also;

Mass of ethanol = 20 g = 0.02 kg

Mass of solvent = 1.00 Kg

Molar mass of solute = 46 gmol-1

Number of moles of solute = 20g/ 46 gmol-1 = 0.43 moles

Molality= 0.43 moles/ 1 kg = 0.43 m

The greater the concentration of a solution, the higher the freezing point of solvent will be depressed. Therefore, higher molality, leader to a greater decrease of the freezing point.

Therefore, the freezing point of water H2O/CH3OH is lower than the freezing point of ethanol.

Using the mmoles of (35)-2,2,-dibromo-3,4-dimethylpentane calculated earlier and the molecular weight of the product (962 g/mol). Predict the theoretical 1 0096 yield of the product in grams. Round to the hundredths place.

Answers

Answer:

The yield of the product in gram is [tex]\mathsf{{w_P}=0.26 \ gram}[/tex]

Explanation:

Given that:

the molecular mass weight of the product = 96.2 g/mol

the molecular mass of the reagent (3S)-2,2,-dibromo-3,4-dimethylpentane is 257.997 g

given that the millimoles of the reagent = 2,7 millimoles = [tex]2.7 \times 10^{-3} \ moles[/tex]

We know that:

Number of moles = mass/molar mass

Then:

[tex]2.7 \times 10^{-3} = \dfrac{ mass}{257.997}[/tex]

[tex]mass = 2.7 \times 10^{-3} \times 257.997[/tex]

mass = 0.697

Theoretical yield = (number of moles of the product/ number of moles of reactant) × 100

i.e

Theoretical yield = [tex]\dfrac{n_P}{n_R}\times 100\%[/tex]

where;

[tex]n_P = \dfrac{w_P}{m_P}[/tex]    and [tex]n_R = \dfrac{w_R}{m_R}[/tex]

Theoretical yield = [tex]\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%[/tex]

Given that the theoretical yield = 100%

Then:

[tex]100\% =\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%[/tex]

[tex]\dfrac{w_P}{m_P}=\dfrac{w_R}{m_R}[/tex]

[tex]{w_P}=\dfrac{w_R \times m_P}{m_R}[/tex]

where,

[tex]w_P[/tex] = derived weight of the product

[tex]m_P =[/tex]the molecular mass of the derived product

[tex]m_R =[/tex] the molecular mass of the reagent

[tex]w_R[/tex] = weight in a gram of the reagent

[tex]{w_P}=\dfrac{w_R \times m_P}{m_R}[/tex]

[tex]{w_P}=\dfrac{0.697 \times 96.2}{257.997}[/tex]

[tex]\mathsf{{w_P}=0.26 \ gram}[/tex]

what would happen to the solvent if a reaction was refluxed without a condenser​

Answers

Answer:

Solvent will be lost as gas and not return into the vessel via condensation.

Explanation:

Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.

The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.

Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR
