Answer to Question #155185 in General Chemistry for David

Question #155185

Ammonium nitrate (NH4NO3) will decompose explosively at high temperatures to form nitrogen, oxygen and water vapor.


2 NH4NO3 → 2 N2 + 4 H2O + O2


If 3.5 x 2023 molecules of ammonium nitrate decompose during the reaction, how many liters of water vapor at STP would also form?

findn(NH4NO3)=3.5∗1023/6∗1023=0.58mol.n(H2O)=2n(NH4NO3)=2∗0.58=1.16molV(H2O)=Vm∗n=1.16∗22.4=26.1dm3
