(a) `A` solution is prepared by dissolving `10g` of non-volatile solute in `180g` of `H_(2)O`. If the relative lowering of vapour pressure is `0.005`, find the molar mass of the solute.   (b) How many grams of sucrose `(C_(12)H_(22)O_(11))`must be dissolved in `90g` of water to produce a solution over which the relative humidity is `80%`? Assume the solution is ideal.
