Dear Akshat Sinha,
We can find the molality by the following steps:-
Let the weight of soln. be 100 grams. then the weight of H2SO4 will be 98 grams...
therefore,we find the no. of moles in 98% H2SO4= weight / molecular mass=98/98=1 mole
Molality= No.of moles of solute/Wt of solvent =1/2
Since we have taken the weight to be 100 g. We need to find it for a kg...
=1/2*1000=500 molal soln.
Hope this helped you dear........
All The Best,.........
I hope that you are surely going to approve my answer by clicking 'Yes' given below..........
