Calculate the mass percent of calcium, phosphorus and oxygen in calcium phosphate Ca3(PO4)

Calculation:

Molecular mass of Ca₃(PO₄) = (3 X 40) + (2 X 31) + (8 X 16)

Molecular mass of Ca₃(PO₄) = 310

Mass percentage of Ca = \[\frac{3\times 40}{310\times 100}\]

Mass percentage of Ca = 38.71%

Mass percentage of P = \[\frac{2\times 31}{310\times 100}\]

Mass percentage of P = 20%

Mass percentage of O = \[\frac{8\times 16}{310}\]

Mass percentage of O = 41.29%
