A 20.0mL sample of CuSO(4) solution was ...

A `20.0mL` sample of `CuSO_(4)` solution was evaporated to dryness, leaving `0.967g` of residue. What was the molarity of the original solution ? `(Cu=63.5)`

A

`48.4M`

B

`0.0207M`

C

`0.0484M`

D

`0.303M`

Text Solution

Verified by Experts

The correct Answer is:
D
Molarity `=(0.967//159.5)/(20//1000) {"Mol" wt. of underset(159.5)(CuSO_(4))}`
`=0.303M`
