Question: Elemental phosphorus is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO 2 and C: 4

Elemental phosphorus is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO ₂ and C:

4 Ca ₅(OP ₄) ₃F + 18 SiO ₂ + 30 C ---> 3 P ₄ + 30 CO + 18 CaSiO ₃ + 2CaF ₂

Suppose a particular semiconductor production plant requires 1500 kg of P ₄. If the recovery of P ₄ from this reaction is 73% efficient, what mass of fluoroapatite is needed?
