Calculate the vapour pressure of solution having 3.42 g of cane-sugar in 180 g water at

40^\circ\text{C}

and

100^\circ\text{C}

. Given that boiling point of water is

100^\circ\text{C}

and heat of vaporisation is

10 \text{ kcal mol}^{-1}

in the given temperature range. Also calculate the lowering in vapour pressure of 0.2 molal cane-sugar at

40^\circ\text{C}
