Calculate the mass percentage composition of copper in copper sulphate.
`[Cu = 63.5, S = 32, O = 16]`

Text Solution

Verified by Experts

Unit formula mass of `CuSO_(4) = 1 (Cu) + 1 (S) + 4 (O) = 1 (64) + 1 (32) + 4 (16) = 64 + 32 + 64 = 160 amu`
Mass % age composition of copper
`= 64/160 xx 100 = 40%`
