Question

A solution of glycerol (C₃H₈O₃) in water was prepared by dissolving some glycerol in 500 g of water. This solution has a boiling point of 100.42°C while pure water boils at 100°C. What mass of glycerol was dissolved to make the solution ? (K_b for water = 0.512 K kg mol^-1)

Answer 1

 (W_B) = Mass of glycerol = ?

(W_A) = Mass of solvent = 500 g

Solution was prepared by dissolving some glycerol in water. (100.12 - 100)

Weight of glycerol = 37.73 g
