Calculate the mole fraction of `H_(2)SO_(4)` in a solution containing `98% H_(2)SO_(4)` by mass.

Explanation

Mole fraction is the ratio of number of moles of one component to the total number of moles of all the components in the solution.. Mole fraction of a component =
`("Number of moles of the component")/("Total number of moles of all the components in the solution")`
Mass of water `" " =2 gm`
Moles of water `=(2)/(18)=0.11 " " (M. Wt. of H_(2)O0=18)`
Mass of `H_(2) SO_(4) " " 98 gm`
Mols of `H_(2)SO_(4) " "(98)/(98)=1 (Mol Wt. of H_(2)SO_(4)=98)`
Moles of fraction of `H_(2)SO_(4)=(1)/(1.0+0.11)=0.9`
