A solution containing `30 g` of a non-volatile solute in exactly `90 g` of water has a vapour pressure of `21.85 mm` of `25^(@)C` . Further `18 g` of water is then added to the solution, the new vapour pressure becomes `22.15 mm` of `Hg` at `25 C`. Calculate the (a) molecular mass of the solute and (b) vapour pressure of water at `25^(@)C`.
