Ammonium carbonate decomposes upon heating according to the following balanced equation:
(NH4)2CO3(s)?2NH3(g)+CO2(g)+H2O(g)

Calculate the total volume of gas produced at 24.0?C and 1.05atm by the complete decomposition of 11.9g of ammonium carbonate

Answer :

Answer : The total volume of gas produced are, 11.5 L

Explanation :

First we have to calculate the moles of ammonium carbonate.

[tex]\text{Moles of }(NH_4)_2CO_3=\frac{\text{Mass of }(NH_4)_2CO_3}{\text{Molar mass of }(NH_4)_2CO_3}[/tex]

Molar mass of [tex](NH_4)_2CO_3[/tex] = 96.094 g/mol

[tex]\text{Moles of }(NH_4)_2CO_3=\frac{11.9g}{96.094g/mol}[/tex]

[tex]\text{Moles of }(NH_4)_2CO_3=0.124mol[/tex]

Now we have to calculate the moles of total gas.

The given balanced chemical reaction is:

[tex](NH_4)_2CO_3(s)\rightarrow 2NH_3(g)+CO_2(g)+H_2O(g)[/tex]

From the balanced chemical reaction we conclude that,

As, 1 mole of [tex](NH_4)_2CO_3[/tex] react to give 4 mole of gas

So, 0.124 mole of [tex](NH_4)_2CO_3[/tex] react to give [tex]0.124\times 4=0.496[/tex] mole of gas

Now we have to calculate the volume of gas.

Using ideal gas equation:

[tex]PV=nRT[/tex]

where,

P = Pressure of gas = 1.05 atm

V = Volume of gas = ?

n = number of moles = 0.496 mole

R = Gas constant = [tex]0.0821L.atm/mol.K[/tex]

T = Temperature of gas = [tex]24.0^oC=273+24.0=297.0K[/tex]

Putting values in above equation, we get:

[tex]1.05atm\times V=0.496mole\times (0.0821L.atm/mol.K)\times 297.0K[/tex]

[tex]V=11.5L[/tex]

Thus, the total volume of gas produced are, 11.5 L

The total volume of all the gases produced in the combustion of 11.9g ammonium carbonate has been 12.02 L.

From the balanced chemical equation, 1 moles of ammonium carbonate produced 2 moles ammonia, 1 mole carbon dioxide, and 1 mole water.

The available ammonium carbonate has been 11.9 grams. The moles of ammonium carbonate has been:

Moles = [tex]\rm \dfrac{Weight}{Molecular\;weight}[/tex]

Moles of ammonium carbonate = [tex]\rm \dfrac{11.9\;g}{96.09\;g/mol}[/tex]

Moles of ammonium carbonate = 0.123 mol.

The moles of gases produced by 0.123 mol of ammonium carbonate has been:

  • 1 mole ammonium carbonate = 2 moles ammonia

0.123 moles ammonium carbonate = 0.247 moles ammonia

  • 1 mole ammonium carbonate = 1 mole carbon dioxide

0.123 moles ammonium carbonate = 0.123 moles carbon dioxide

  • 1 moles ammonium carbonate = 1 moles water

0.123 moles ammonium carbonate = 0.123 moles water.

The total moles of gases produced:

= Moles of ammonia + moles of carbon dioxide + moles of water

= 0.247 + 0.123 + 0.123

= 0.493 moles.

According to the ideal gas equation,

PV = nRT

P = pressure = 1 atm.

V = volume

n = moles of gas = 0.493 mol.

R = constant = 0.08206 L.atm/mol. K

T = temperature = 297.15 K.

Substituting the values:

1 × Volume = 0.493 × 0.08206 × 297.15

Volume = 12.02 L.

The total volume of all the gases produced in the combustion of 11.9g ammonium carbonate has been 12.02 L.
