Problem 117P

PROBLEM 117P

Ammonium carbonate decomposes upon heating according to the balanced equation:

(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)

Calculate the total volume of gas produced at 22 °C and 1.02 atm by the complete decomposition of 11.83 g of ammonium carbonate.

Step-by-Step Solution:
Step 1 of 3

Solution 117P

Given:

(NH4)2CO3(s) → 2NH3(g) + CO2(g) + H2O(g)

Mass of ammonium carbonate = 11.83 g

Pressure = 1.02 atm

Temperature = 22oC

We will have to find out the volume of gas produced.

Explanation:

From the ideal gas equation, it is known that,

PV=nRT

Or, V=(ntotal)RT/P

MW of( NH4)2CO3 (s)=96 gram/mole

moles of ( NH4)2CO3(s)= 11.83 grams of (NH4)2CO3(s)(1 mole of ( NH4)2CO3(s)

                               ------------------------------------------------------------------------  =0.1232

                                                 (96 grams)

ntotal of gases produced=moles of NH3 + moles of CO2(g) + moles of H2O (g)

Using the stoichiometry of the balanced eq:

moles of NH3=0.1232 (2)=0.2465

moles of CO2= 0.1232

moles of H2O=0.1232

ntotal of gases produced= 0.1232 +0.1232+ 0.2465=0.4929

273 +Celsius=Kelvin

273 +22 =295 Kelvin

V=(ntotal)RT/P=   = 11.71L

Thus the total volume of gas is 11.71 L
