Question

Calculate the percentage of phosphorus in:
Calcium phosphate Ca3(PO4)2

Open in App
Solution

Relative molecular mass of Ca3(PO4)2
=(40.07×3)+(30.9×2)+(16×8)
=120.21+61.8+128
=310.01
310.01gCa3(PO4)2 contains 61.8gP
So, 100gCa(H2PO4)2 contains

%ofphosphorous=2×31310.17×100

%ofPhosphorous=19.98%


The % of P in Ca(H2PO4)2 is 19.98%
