What is the percentage composition of each element is zinc-phosphate `Zn_(3) (PO_(4))_(2)`? `(Zn = 65.5, P = 31, O = 16)`

Text Solution

Verified by Experts

`Mw` of `Zn_(3) (PO_(4))_(2) = 65.5 xx 3 + 2[31 + 16 xx 4]`
`= 196.5 + 2 xx 95 = 386.5`
`% of Zn = (196.5 xx 100)/(386.5) = 50.84%`
`% of P = (62 xx 100)/(386.5) = 16.04%`
`% of O = (128 xx 100)/(386.5) = 32.12%`
