Textbook Problem

hen ammonium carbonate is heated, three gases are produced by its decomposition.

msp;  ${\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{CO}}_{\text{3}}\left(s\right) {\text{2NH}}_{\text{3}}\left(g\right)+{\text{CO}}_{\text{2}}\left(g\right)+{\text{H}}_{\text{2}}\text{O}\left(g\right)$

at total volume of gas is produced, measured at $\text{453 }°\text{C}$and $\text{1}.0\text{4}$atm, if $\text{52}.0\text{ g}$of ammonium carbonate is heated?
