Question

what will be molality of aq.urea solution of its vapour pressure at 100°C is 750 torr​

Answer 1

Answer:

molality of aq.urea solution of its vapour pressure at 100°C is 750 torr.

C6H12O6 solution has vapour pressure equal to 40 Torr at certain temperature. Vapour pressure of H2O is 40.8 Torr at same temperature. If this solution is cooled to 0.93 degrees. What mass of ice will be separated out (Kf =1.86) .
