Asked by Aarohi
Assuming that Raoults law is followed what would be the vapour pressure of a solution formed when 40g of sugar (molecular mass 342g) is dissolved in 360ml of water at 25oC? At 250C,the vapour pressure of water is 20mm and the density is 1g/ml.

mols sugar = grams/molar mass = ?
mols H2O = grams/molar mass = ?
XH2O = mols H2O/total mols = ?
pH2O = XH2O*PoH2O
Post your work if you get stuck.
