Calculate the mole fraction of H(2)SO(4)...

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

Text Solution

Verified by Experts

Mass of water = 2 gm
Moles of water `= (2)/(18) = 0 . 11` (M.Wt. of `H_(2) O = 18` )
Mass of `H_(2) SO_(4)` = 98
Moles of `H_(2) SO_(4) = (98)/( 98) = 1 ` (Mol . Wt. of `H_(2) SO_(4) = 98` )
Mole fraction of ` H_(2) SO_(4) = (1)/(1.0 + 0.11) = 0.9`
