Calculate the mass percent of calcium, phosphorus and oxygen in calcium phosphate Ca 3 → PO4) 2 .

Question

Philoid · Accepted Answer

The molar mass of Ca₃→PO₄)₂ is 40x3 + →31 + 16x4) x 2 = 310.

The mass percent is calculated by

Mass % of Ca = x 100 = 38.71%

Mass % of P = x 100 = 20%

Mass % of O = x 100 = 41.29%
