Calculate the percentage of phosphorus in Calcium phosphate `Ca_3 (PO_4)_2`.

Text Solution

Verified by Experts

Relative molecular mass of calcium phosphate `Ca_3(PO_4)_2`
=(40 x 3) + (31 x 2) + (16 x 8)
=120+62 +128
= 310
Since , 310 gm of `Ca_3(PO_4)` contains 62 gm of phosphorus .
Therefore , 100 gm of `Ca_3(PO_4)= 62/310xx100`=20%
