Question

percentage compositions of Ca3(PO4)2

​

Answer 1

Answer:

Ca3(po4)2

Explanation:

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

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

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

Percent of oxygen = 310/128 ×100=41.21%

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

For 2 phosphate molecule=94.97×2=189.94g/mol

Ca3(po4)2 = 189.94/310×100=61.24%

the percentage composition of ca3(po4)2=61.24%
