Question

Calculate the vapour pressure of solution having 3.42 g of canesugar in 180 g water at 40oc40oc and 100oc100oc. Given that, the boiling point of water is 100oc100oc and heat of vaporisation is 10 kcal mol1mol1 in the given temperature range. Also, calculate the lowering in vapour pressure of 0.2 molal cane-sugar at 40oc
