If we have `10` molal urea solution, Calculate mole fraction of urea in this solution `&` also calculated `% W//W` of urea `(MW=60)`.

Text Solution

Verified by Experts

10 moles urea in 1000 g of water
`X_(Area)=10/(10+100/18)=10/65.55=0.1526`
% w/w weight of urea `=(10xx60)/(10xx60+1000)xx100=37.5%`
