The volume of 0.5 M `H_(3)PO_(4)` that completely dissolved 3.1 g of copper carbonate is (molecular mass of copper carbonate`=124gmol^(-1))`

A

`55.5mL`

B

`45.5mL`

C

`35.5mL`

D

`33.3mL`

Text Solution

Verified by Experts

The correct Answer is:
D
`CuCO_(3) rArr (3.1)/(123.5//2) xx 1000`
`mEq CuCO_(3) -= mEq H_(3)PO_(4)`
`(3.1)/(124//2) xx 1000 =(0.5 xx 3) xx V rArr V = 33.3 mL`
