(a) A 10% solution (by mass) of sucrose in water has freezing point of 269.15K. Calculate the freezing point of 10% glucose in water, if the freezing point of pure water is 273.15K.
Given: (molar mass of sucrose=342 g `mol^(-1)`)
(Mola mass of glucose =180g `mol^(-1)`)
(b) Define the following terms:
(i) Molality (m)
(ii) Abnormal molar mass

Explanation

(a) Refer solution to Particle Problem 59 (Page 71)
