`100mL` of `H_(2)SO_(4)` solution having molarity `1M` and density `1.5g//mL` is mixed with `400mL` of water. Calculate final m plarity of `H_(2)SO_(4)` solution, if final density is `1.25g//mL`?

Options

A. `4.4M`
B. `0.145M`
C. `0.52M`
D. `0.227M`

Answer

4

Explanation

Total moles of `H_(2)SO_(4)=0.1` mole
Total volume `=(150+400)/(1.25)=-(550)/(1.25)=440`
`:." "M=(0.1)/(440)xx1000=(1)/(4.4)=0.227M`
