A solution containing `30g` of a nonvolatile solute in exactly `90g` water has a vapour pressure of `21.85 mm Hg` at `25^(@)C`. Further `18g` of water is then added to the solution. The resulting solution has vapour pressure of `22.18 mm Hg` at `25^(@)C`. calculate (a) molar mass of the solute, and (b) vapour pressure of water at `25^(@)C`.
