Question

Heptance and octane form an ideal solution at 373 k, the vapour pressures of the pure liquids at this terperatureare 105.2 kpa and 46.8 kpa respectively. If the solution contains 25g of heptance and 28.5g of octane, calculate(i) vapour pressure exerted by heptane(ii) vapour pressure exerted by solution(iii) mole fraction of octane in the vapour phase.
