250 g250 g solution of DD-glucose in water contains 10.8%10.8% of carbon by weight. The molality of the solution is nearest to (Given: Atomic Weights are H=1u; C=12 u; O=16 uH=1u; C=12 u; O=16 u)

If mass percentage of glucose in aqueous solution is 18% then molality of glucose in the solution will be3.5 m1.2 m0.5 m4.1 m

A solution of glucose has been prepared by dissolving 1.8 g of glucose in 200 g of water. The boiling point of the solution obtained will be (Kb for water = 0.52 K kg mol–1)

Calculate the mass of water and mass of glucose required to make 250 g of 40% solution of glucose.
