Vitamin K is involved in normal blood clotting. When 1.76 g of vitamin K is dissolved in 25.0 g of camphor, the freezing point of the solution is lowered by 5.89 °C. Look up the freezing point and Kf constant for camphor in the Colligative Constants table. Calculate the molar mass of vitamin K. molar mass: g/mol

Expert Solution
Step 1
Given, the mass of solute vitamin K = 1.76g
Mass of solvent camphor = 25.0g
Depression in freezing point = 5.89oC.
Kf of camphor = 37.7oC/m
Freezing point of camphor =178.4oC.
What is the molar mass of vitamin K?
