Question

A 5% solution (by mass) of cane sugar in water has freezing point of 271K. Calculate the freezing point of 5% glucose in water if freezing point of pure water is 273.15 K.​

Answer 1

Answer:

Calculate the freezing point of 5% glucose in water if freezing point of pure water is 273.15 K. 5% solution (by mass) of cane sugar in water means 5 g of cane sugar is present in (100 - 5)g = 95 g of water. ... Hence, the freezing point of 5% glucose solution is (273.15 - 4.09) K= 269.06 K.
