Convert Atoms to Moles

The first step is to convert atoms to moles. 1 mole of every substance has the same number of particles: 6.022 ×10²³ or Avogadro's Number. The type of particle can be different, in this case it is atoms of silver. Let's create a ratio using this information.

[tex]\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

We are trying to find the mass of 8.23 ×10²³ silver atoms, so we multiply by that number.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

Flip the ratio so the atoms of silver cancel. The ratio is equivalent, but places the other value with units "atoms Ag" in the denominator.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{1 \ mol \ Ag}{6.022*10^{23} \ atoms \ Ag}[/tex]

[tex]8.23 *10^{23} *\frac{1 \ mol \ Ag}{6.022*10^{23} }[/tex]

Condense into one fraction.

[tex]\frac{8.23 *10^{23} }{6.022*10^{23} } \ mol \ Ag[/tex]

[tex]1.366655596 \ mol \ Ag[/tex]

Convert Moles to Grams

The next step is to convert the moles to grams. This uses the molar mass, which is equivalent to the atomic mass on the Periodic Table, but the units are grams per mole.

Let's make another ratio using this information.

[tex]\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

Multiply by the number of moles we calculated.

[tex]1.366655596 \ mol \ Ag*\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

The moles of silver cancel out.

[tex]1.366655596 *\frac {107.868 \ g \ Ag}{1 }[/tex]

[tex]1.366655596 * {107.868 \ g \ Ag}[/tex]

[tex]147.4184058 \ g\ Ag[/tex]

Round

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we calculated, that is the ones place.

The 4 in the tenths place tells us to leave the 7 in the ones place.

[tex]147 \ g\ Ag[/tex]

8.23 ×10²³ silver atoms are equal to approximately 147 grams.

Explanation:

The water is formed from oxygen gas and...hydrogen gas, I'm assuming? It would have been nice for the question to have been a bit more explicit (not blaming you, of course).

Assuming that's the case, our chemical reaction would be:

2H₂(g) + O₂(g) → 2H₂O(l).

We are told that 1 mol of a gas has a volume of 24.0 dm³ at RTP. We can use this relation to determine the number of moles of O₂ gas that reacts given its initial volume, 33.5 dm³.

33.5 dm³ O₂(g)/24.0 dm³/mol = 1.396 mol O₂(g).

Since we are not given any information about H₂(g), or any other reactant for that matter, I am assuming that the O₂(g) is the limiting reactant. According to the equation, the stoichiometric ratio between O₂ and H₂O is 1:2. That is, for every one mole of O₂ that is consumed, two moles of H₂O are formed (i.e., the number of moles of H₂O formed is double the number moles of O₂).

Since 1.396 moles of O₂ reacts, 2(1.396) = 2.792 moles of H₂O are produced. To convert moles of water to grams, we multiply the number of moles of H₂O by the molar mass of H₂O:

(2.792 moles H₂O)(18.015 g/mol) = 50.3 g H₂O.

So, approximately 50.3 grams of water are formed from 33.5 dm³ of oxygen gas at RTP.

Answer:

45 mL

Explanation:

Tenemos los siguientes datos:

V = 1 L

C = 4,5% v/v

El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:

4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol

Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:

4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

Answer: The volume of [tex]NaOH[/tex] required is 25.0 ml

Explanation:

According to the neutralization law,

[tex]n_1M_1V_1=n_2M_2V_2[/tex]

where,

[tex]n_1[/tex] = basicity [tex]HNO_3[/tex] = 1

[tex]M_1[/tex] = molarity of [tex]HNO_3[/tex] solution = 2.00 M

[tex]V_1[/tex] = volume of  [tex]HNO_3[/tex] solution = 50.0 ml

[tex]n_2[/tex] = acidity of [tex]NaOH[/tex] = 1

[tex]M_1[/tex] = molarity of [tex]NaOH[/tex] solution = 4.00 M

[tex]V_1[/tex] = volume of  [tex]NaOH[/tex] solution =  ?

Putting in the values we get:

[tex]1\times 2.00\times 50.0=1\times 4.00\times V_2[/tex]

[tex]V_2=25.0ml[/tex]

Therefore, volume of [tex]NaOH[/tex] required is 25.0 ml

The volume of 4.00 M NaOH is required to exactly neutralize 50.0 ml of a solution of a 2.00 M solution of [tex]HNO_3[/tex] is 25.0 ml.

[tex]HNO_3[/tex] is nitric acid also known as the spirit of niter. It is colorless in its original form but appears yellow-colored.

By the neutralization law

[tex]n_1M_1V_1 = n_2M_2V_2[/tex]

n1 = 1

M1 = 2.00

M2 = 4.00

V1 = 50.0 ml

n2 = NaOH = 1

Putting the value in the formula

[tex]1 \times 2.00 \times 5.00 ml = 1 \times 4.00 \times V_2\\\\V_2 = 25.0\; ml[/tex]

Thus, the volume of NaOH required is 25.0 ml.

Answer:

The energy of the wave particle is 3.058 x 10⁻²³ J.

Explanation:

Given;

Answer:

0.137 M NH3

Explanation:

First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.

Answer:

H = 226,311.66J

Explanation:

Hello there!

In this case, according to the thermodynamic path ice takes up to steam:

1. Ice (-15°C) --> Ice (0°C) H1

2. Ice (0°C) ---> Water (0°C) H2

3. Water (0°C) --> Water (100°C) H3

4. Water (100°C) --> Steam (100°C) H4

5. Steam (100°C) --> Steam (145°C) H5

It is possible for us to infer that H1, H3 and H5 are computed by means of the mass, specific heat and change in temperature as sensible heat. On the flip side, H2 and H4 are computed as latent heat. Thus, we proceed as follows:

[tex]H1=72.3g*2.093\frac{J}{g\°C}(0+15)\°C=2269.86J\\\\H2=72.3g*334.1\frac{J}{g}=24155.43J\\\\H3=72.3g*4.184 \frac{J}{g\°C}*(100-0)\°C=30250.32J\\\\H4=72.3g*2255.83\frac{J}{g}=163096.51J\\\\H5=72.3g* 2.010 \frac{J}{g\°C}*(145-100)\°C=6539.54J[/tex]

Then, we add them up to obtain the total heat:

[tex]H=H1+H2+H3+H4+H5\\\\H=2269.86J+24155.43J+30250.32J+163096.51J+6539.54J\\\\H=226311.66J[/tex]

Answer:

The new volume will be 9.24 mL.

Explanation:

Charles's law determines that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

So, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

When studying an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{8.70 mL}{318.2 K} =\frac{V2}{337.8 K}[/tex]

Solving:

[tex]V2=337.8K*\frac{8.70 mL}{318.2 K}[/tex]

V2= 9.24 mL

The new volume will be 9.24 mL.

Explanation:  the scientific notation used to calculate a mole is 6.022 x 1023.

Avogadro's number in scientific notation is 6.023×10²³ atoms, molecules, moles.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.
