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.
