Upon fully dissolving 2.0 g of a metal in sulfuric acid, 6.8 g of the metal sulfate is formed. The equivalent weigth of the metal is-

A

`13.6 g`

B

`20.0g`

C

`4.0g`

D

`10.0g`

Text Solution

Verified by Experts

The correct Answer is:
B
Equivalents of metal=Equivalents of metal sulphate
`("wt.of metal")/("Eq. wt. of metal")("wt. of metal sulphate")/("Eq. wt. metal sulphate")`
`(2)/(x)=(6.8)/(x +48)`
`6.8x=2x+96`
`4.8x=96`
`x=(96)/(4.8)=20`
