The production capacity for acrylonitrile (C3H3N) in the United States exceeds 2 million pounds per year. Acrylo-nitrile, the building block for polyacrylonitrile fibers and a variety of plastics, is produced from gaseous propylene, ammonia, and oxygen:
2C3H6(g) + 2NH3(g) + 3O2(g) → 2C3H3N(g) + 6H2O(g)
a. What mass of acrylonitrile can be produced from a mixture of 1.00 kg of propylene (C3H6), 1.50 kg of ammonia, and 2.00 kg of oxygen, assuming 100% yield?
b. What mass of water is produced, and what masses of which starting materials are left in excess?
