What is the molarity of `H_(2)SO_(4)` solution that has a density 1.84 g/c c at `35^(@)`C and contains 98% by weight?

Options

A. 4.18 M
B. 8.14 M
C. 18.4 M
D. 18 M

Answer

C

Explanation

`"Molarity"=("wt. of solute")/("mol. wt.")xx(1000)/("vol. of solution (in ml.)")`
`("Volume of solution "=("mass")/("density")=(100)/(1.84)="54.34 ml")`
`"Now molarity "=(98)/(98)xx(1000)/(54.34)="18.4 M"`
