How many grams of sulphuric acid is to be dissolved to prepare 200 ml acqueous solution having concentration of `[H^(+)]` ions 1 M at `25^(@)C`.

A

4.9 g

B

19.6 g

C

9.8 g

D

0.98 g

Text Solution

Verified by Experts

The correct Answer is:
C
`[H^(+)]=2xx[H_(2)SO_(4)]`
`rArr[H_(2)SO_(4)]=0.5`
`0.5=(wxx1000)/(98xx200)`
`w=49/(5)=9.8`
