The depression in the freezing point of the solution is given by
freezing point of water freezing point of solution
K
Molar masses of glucose and sucrose are g/mol and g/mol respectively.
g of solution will contain g of glucose or g of sucrose.
Number of moles of glucose moles
Number of moles of sucrose moles
Mass of solvent = total mass of solution - mass of solute g or kg
Molality of sucrose solution m
For glucose solution,
Freezing point of glucose solution in water = freezing point of water - K
