9.8 g of `H_(2)SO_(4)` is present in two litres of a solution. The molarity of the solution is,

A

`0.1M`

B

`0.05M`

C

`0.2M`

D

`0.01M`

Text Solution

Verified by Experts

The correct Answer is:
(b)
Weight of `H_(2)S0_(4) (w) = 9.8g`
Molecular weight of `H_(2)SO_(4) (m) = 2 + 32 + 64 = 98g`
Volume of solution V= 2L = 2000 mL
Molarity (M) = M=`(w xx 1000)/(m xx v)=(9.8 xx 200)/(98 xx 200)=0.05M`
