Question

Vitamin D is one of the lipid soluble
vitamins. When 1.50 g of vitamin D
is dissolved in 20.0 g of camphor,
the freezing point of the solution is
lowered by 7.18 K. Calculate the
molecular mass of vitamin D. (The
freezing point depression constant
for camphor is 37.8 K•m-1).

Expert Solution

Step 1

A solution is formed by homogenous mixing of solute and solvent. The properties of solution that are affected by number of solute particles in the solution are referred as the colligative property of the solution. The colligative properties of a solution have deviation from the property of the solvent depending on the number of solute particles. The colligative properties are affected by the solute are boiling point, freezing point, vapor pressure and osmotic pressure.
