Calculate the mass per cent of calcium, ...

Calculate the mass per cent of calcium, phosphorus and oxygen in calcium phosphate `Ca_(3)(PO_(4))_(2)`.

Text Solution

Verified by Experts

Molecular mass of calcium phosphate `Ca_(3)(PO_(4))_(2)` is :
`3 xx` Atomic mass of `Ca + 2 xx` Atomic mass of `P + 8 xx` Atomic mass of O.
`= (3xx40 u)+2(2xx31u)+(8xx16u)=310u`
Mass percent of calcium `(Ca)=((12u))/((310u))xx100=38.71%`

Mass percent of phosphorus `(P)=((62u))/((310u))xx100=20.0%`

Mass percent of oxygen `(O)=((128u))/((310u))xx100=41.29%`.
