Dear student,
98% by weight H2SO4 means 98gm of H2SO4 is present in 100 gm of solution.
The solution consists of solvent and solute. Here, since 98gm is of H2SO4 then 2gm is water ( if nothing is given then assume by default water as one of the solvent or solute as per the requirement ).
So, 98gm H2SO4 is = 1mol.
And 2 gm water is = 2/18 = 0.11mol
So, mole fraction of H2SO4 is = 1/(1+0.11) = 0.9009
