Question

calculate the mass percentage of calcium and phosphorus in calcium phosphate​

Answer 1

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 = 310/120×100=38.71%

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

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