Question

Calculate the formula weight of a nonelectrolyte, 5 g of which dissolved in 200 g of water gives solution which has a freezing point of negative 1.04 degrees celsius.

Answer 1

∆T = K_F·m

where K_F is the molal freezing point depression constant;

m - the molality of the solute.

In order to solve this task, data on the K_F (molal freezing point depression constant) is required.
