Question

calculate the %age composition of each element in Calcium phosphate
give step by step explaination ​

Answer 1

Answer:

Ca = 38.71%,P = 20.0%,O = 41.29%

Explanation:

Molecular formula of calcium phosphate is Ca

3

(PO

4

)

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%
