Question

An important step in the industrial production of phosphorous fertilizers is the conversion of fluorapatite , Ca5(P04)3F, to calcium dihydrogen phosphate: 2Ca5(P04)3F(s) + 7H2S04(aq) rightarrow 3Ca(H2P04)2(aq) + 7CaS04(aq) + 2HF(g) When fluorapatite is reacted with excess H2SO4(aq) the reaction gives an 88.4 % yield of calcium dihydrogen phosphate. Calculate the mass of flurapatite required to produce 2.56 times 107 g of calcium dihydrogen phosphate. Molar masses: Ca5(P04)3F = 504.31 g/mol; Ca(H2P04)2 = 234.05 g/mol
