Gas Stoichiometry

Question

Please consider the following UNBALANCED reaction for the decomposition of trinitroglycerin: C3H5N3O9 = N2 + CO2 + H20 + O2. What mass of trinitroglycerin would be required to produce 50 L o2 if trinitroglycerin spontaneously decomposes at 60 C? Assume the pressure remains constant.

Answer 1

Balance equation: 2C₃H₅N₃O₉ = 6CO₂ + 3 N₂ + 5H₂O + 1/2 O₂

Use gas data to find moles of O₂ using IGL n = (1 stm)(50 liter)/((.0821)(333.15K))

Stoichiometry:

Moles of O₂ (2 moles of TNG/ .5 moles of O₂)(227 g/mole of TNG) = g of TNG
