Concentrated aqueous solution of sulphuric acid is `98 %` by mass and has density of `1.80 "g mL"^(-1)`. What is the volume of acid required to make one liter `0.1 M H_(2)SO_(4)` solution ?

Options

A. 11.10 mL
B. 16.65 mL
C. 22.20 mL
D. 5.55 mL

Answer

D

Explanation

`"M of original "H_(2)SO_(4)=((w//w)%xx" density "xx10)/("G.M.Wt of "H_(2)SO_(4))`
`=(98xx1.8xx10)/(98)=18M`
`"Molarity for dilution is "M_(1)V_(1)=M_(2)V_(2)`
`18xxV_(1)=0.1xx1000`
`V_(1)=(0.1xx1000)/(18)=5.55ml`
