question

(a) a 10% solution (by mass) of sucrose in water has a freezing point of 269·15 k. calculate the freezing point of 10% glucose in water if the freezing point of pure water is 273·15 k.
given :
(molar mass of sucrose = 342 g mol-1)
(molar mass of glucose = 180 g mol-1)
(b) define the following terms :
(i) molality (m)
(ii) abnormal molar mass
