Elemental phosphorus is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO2 and C: 4 Cas (PO4)3F + 18 SiO2 + 30 C → 3 P4 + 30 CO + 18 CaSiO3 + 2 CaF2 Suppose a particular semiconductor production plant requires 2100 kg of P4. If the recovery of P4 from this reaction is 79% efficient, what mass of fluoroapatite is needed? Mass = kg
