Ammonium nitrite undergoes thermal decomposition to produce only gases: NH₄NO₂ (s) → N₂ (g) + 2H₂O (g)
What volume (L) of gas is produced by the decomposition of 35.0 g of NH₄NO₂(s) at 525 °C and 1.5 atm?

Question

Quizplus · Accepted Answer

The molar mass of NH₄NO₂ is 64 g/mol. 35.0 g corresponds to 0.547 mol. The decomposition produces 3 moles of gas per mole of NH₄NO₂, so 0.547 mol produces 1.641 mol of gas. Using the ideal gas law (PV=nRT) at 525°C (798 K) and 1.5 atm, the volume is approximately 48 L.
