Solution: Phosphorus can be prepared from calcium phosphate by the following reaction:2Ca3(PO4)2(s) + 6SiO2(s) + 10C(s) → 6CaSiO3(s) + P4(s) + 10CO(g)Phosphorite is a mineral that contains Ca 3(PO4)2 plus other non-phosphorus-containing compounds. What is the maximum amount of P4 that can be produced from 1.0 kg of phosphorite if the phorphorite sample is 75% Ca3(PO4)2 by mass? Assume an excess of the other reactants.

Problem

Phosphorus can be prepared from calcium phosphate by the following reaction:

2Ca3(PO4)2(s) + 6SiO2(s) + 10C(s) → 6CaSiO3(s) + P4(s) + 10CO(g)

Phosphorite is a mineral that contains Ca 3(PO4)2 plus other non-phosphorus-containing compounds. What is the maximum amount of P4 that can be produced from 1.0 kg of phosphorite if the phorphorite sample is 75% Ca3(PO4)2 by mass? Assume an excess of the other reactants.
