6 grams of sodium chloride (NaCl) is dissolved to create 0.5 L of solution. What is the
molarity of this solution?
Answers
Answer:
0.206M
Explanation:
Molarity, which refers to the molar concentration of a substance can be calculated using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the provided information, mass = 6grams, volume = 0.5L
Since molar mass of NaCl = 23 + 35.5
= 58.5g/lol
Mole = mass/molar mass
Mole = 6/58.5
Mole = 0.103mol
Hence;
Molarity = 0.103/0.5
Molarity = 0.206M
If there are 0.090 moles of sugar (C₁₂H₂₂O₁₁) in the average can of soda, how many sugar molecules would this be
Answers
Given :
There are 0.090 moles of sugar (C₁₂H₂₂O₁₁) in the average can of soda.
To Find :
How many sugar molecules would this be ?
Solution :
We know, in 1 mole of any compound their are [tex]6.022\times 10^{23}[/tex] molecules of that compound.
So, number of molecules in 0.090 moles of compound is :
[tex]n = 0.090 \times 6.022 \times 10^{23}\\\\n = 5.42\times 10^{22}[/tex]
Therefore, number of molecules in 0.090 moles of compound is [tex]5.42 \times 10^{22}[/tex] .

White light is made of a spectrum of various colors.
D)
White light gets hotter when it passes through prisms.
Answers
Answer:
White light is made of a spectrum of various colors.
Explanation:
As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. ... As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.

What is the formula mass/molar mass of H2CO2
Answers
H - 1.01
C - 12.01
0 - 16.00
2(1.01) + 12.01 + 2(16.00) = 46.03 g/mol
Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, 46.03 g/mol is the formula mass/molar mass of H[tex]_2[/tex]CO[tex]_2[/tex].
What is mass?Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.
molar mass of Hydrogen - 1.01
molar mass of Carbon- 12.01
molar mass of Oxygen - 16.00
Molar mass =2×molar mass of H +1×molar mass of C+2×molar mass of O
substituting all the values, we get
2(1.01) + 12.01 + 2(16.00) = 46.03 g/mol
Therefore, 46.03 g/mol is the formula mass/molar mass of H[tex]_2[/tex]CO[tex]_2[/tex].

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433
Answers
Answer:
0.0493 moles de Titanio
Explanation:
Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:
Volumen de la esfera:
Volumen esfera = 4/3π * Radio³
Volumen = 0.5236cm³
En m³ (1m³ = 1x10⁶cm³):
0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³
Masa en gramos:
5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio
Moles -Masa molar Ti: 47.867g/mol-:
2.36g de Titanio * (1mol / 47.867g) =

Jay painted the inner four walls of a box. Then he put an ice block into it such that it did not touch the walls, but he couldn't do the same when he put water in that box. Why?
Answers
Answer:
Liquid takes the shape of container, so it will always touch the walls of the box in which you put it.
Explanation:
We know that a solid has a definite shape and a definite volume hence it occupies only its own volume in the box, it does not touch the walls of the box.
However, a liquid does not have a definite shape and volume. It occupies the volume of the box. Therefore, the liquid water must definitely touch the walls of the box.

Answers
Answer:
[tex]\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}[/tex]
Explanation:
Density is found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the object is 11 grams and the volume is 13 milliliters.
[tex]m= 11 \ g \\v= 13 \ mL[/tex]
Substitute the values into the formula.
[tex]d= \frac{11 \ g}{13 \ mL}[/tex]
Divide.
[tex]d=0.846153846 \ g/mL[/tex]
Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.

1 loop in the primary coil and 8 loops in the secondary. If the secondary voltage is 120 V, what must be the primary voltage
Answers
Answer:
[tex] V_{p} = 15 V [/tex]
Explanation:
Given the following data;
Number of loops in primary coil, Np = 1 loop.
Number of loops in secondary coil, Ns = 8 loops
Voltage in secondary coil, Vs = 120V
To find the voltage in the primary coil, Vp;
Transformer ratio is given by the formula;
[tex] \frac{V_{p}}{V_{s}} = \frac{N_{p}}{N_{s}}[/tex]
Making Vp the subject of formula;
[tex] V_{p} = \frac{N_{p}}{N_{s}} * V_{s} [/tex]
Substituting into the equation, we have;
[tex] V_{p} = \frac{1}{8} * 120 [/tex]
[tex] V_{p} = \frac{120}{8} [/tex]
[tex] V_{p} = 15 V [/tex]
Therefore, the voltage in the primary coil, Vp is 15 Volts.

Group 1 has charges of 1+
Group 2 has 2+
Group 3 has 3+
Group 4 has +/-4
Group 5 has -3
Group 6 has -2
Group 7 has -1
Group 8 doesn’t form ions because they don’t react.
Do you notice a pattern? Group 4 is like the middle and both sides.
For example, lets look at the first question:
Na (Sodium) is in group 1. This means that its ions have a 1+ charge. And Cl (Chlorine) in in group 7, meaning it has a 1- charge.
2) In the next step we try to cancel out the charges by finding the lowest common multiple. But, in this case, there is no need because 1+ and 1- cancel out to have an overall charge of 0 when they are in a compound.
3) Lastly, we put the two elements together. If we multiplied it to cancel the charges in the previous step, then we need to put the number we multiplied it by in front of it.
Lets do another example:
Magnesium is in group 2, therefore it forms a 2+ ion.
Oxygen is in group 6, therefore it forms a 2- ion.
Both charges cancel out and we are left with MgO.
The next example involved the 2nd step.
Lithium is in group 1, so it forms 1+ ions.
Oxygen is in group 6, so it forms 2- ions.
In order to cancel out the charges, we have to multiply lithium by to to get Li2 with a 2+ charge.
Now the charges cancel and we can put them together to get Li2O.

If 3.50 moles of sodium chloride is added to your food, how many grams is added?
Answers
Answer:
204.8g
Explanation:
The number of moles of a substance is related to its mass and molecular mass as follows:
mole (n) = mass (m) ÷ molar mass (MM)
According to this question, 3.50 moles of sodium chloride (NaCl) is added to a food.
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Using mole = mass/molar mass
Mass = molar mass × mole
Mass = 58.5g/mol × 3.5mol
Mass = 204.75
Mass = 204.8grams.
Therefore, 204.8grams of NaCl or common salt was added to the food.
