Question

Calculate the mass precentage of calcium and phosphorus in calcium phosphate

Answer 1

Answer:

This is your answer

Explanation:

Molecular formula of calcium phosphate ➡ Ca3(PO4)2.

Molar mass = 3(40)+2(31)+8(16)=310 g/mol.

Percent of calcium =310120×100=38.71%

Percent of phosphorus =31062×100=20.0%

Answer 2

Answer:

Molecular formula of calcium phosphate is Ca3(PO4)2.

Its molar mass is 3(40)+2(31)+8(16)=310 g/mol.

Percent of calcium = 120/310×100=38.71%

Percent of phosphorus = 62/310 ×100=20.0%

Percent of oxygen =128/310 ×100=41.29%
