Calculate percentage composition of the elements in calcium phosphate Ca3(PO4)2.

Question

KnowledgeBoat · Accepted Answer

Relative molecular mass of Calcium phosphate, Ca3(PO4)2 = 3 x 40 + 2(31 + 4 x 16) = 120 + 2(31 + 64) = 120 + 190 = 310 amu 310 g of Ca3(PO4)2 contains 120 g of Calcium ∴ 100 g of Ca3(PO4)2 contains g of Calcium = = 38.70 % of Calcium. 310 g of Ca3(PO4)2 contains 62 g of Phosphorus ∴ 100 g of Ca3(PO4)2 contains g of Phosphorus = = 20 % of Phosphorus. 310 g of Ca3(PO4)2 contains 128 g of Oxygen. ∴ 100 g of Ca3(PO4)2 contains g of Oxygen. = = 41.3 % of Oxygen. ∴ In Ca3(PO4)2 : Ca = 38.70%, P = 20% and O = 41.3%
