(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
