What is the molality of a solution of 12 g of sodium chloride dissolved in 101 g of water that exhibits a freezing point depression of 3.4 C? The molal freezing point depression constant for water is 1.86 C m-1. Show all of your calculations.
Expert Solution
Step 1
Mass of NaCl = 12 g
Mass of water = 101 g
Freezing point depression, ∆Tf = 3.4oC
Kf water = 1.86 oC/m
i = 2 for NaCl
