Answer to Question #56049 in General Chemistry for sue

Question

How many liters of water vapor are produced when 23.6 g of NH4NO3 decomposes?
Express your answer with the appropriate units.

V=???

Answer 1

2NH₄NO₃ = 2N₂ + O₂ + 4H₂O
M(NH₄NO₃ ) = 14*2 + 1*4 + 16*3 = 80 (g/mol)
n (NH₄NO₃ ) = m/M = 23.6/80 = 0.295 (mol)
n(H₂O) = 2* n(NH₄NO₃ ) = 0.59 (mol)
V(H₂O) = n * Vm = 0.59 * 22.4 = 13.216 (l)

Answer
V (H₂O) = 13.216 l
