Acrylonitrile (C₃H₃N) is the starting material for many synthetic carpets and fabrics. It is produced by the following reaction:
2 C₃H₆ (g) + 2 NH₃ (g) + 3 O₂ (g) → 2 C₃H₃N (g) + 6 H₂O (g)
If 12.0 g C₃H₆, 10.0 g NH₃, and 5.0 g O₂ react, what mass of acrylonitrile can be produced, assuming 100% yield?
