Question

Osmotic pressure is a colligative property.

a) What is osmotic pressure? (1)

b) 1.00 g of a non-electrolyte solute dissolved in 50 g of benzene lowered the freezing point of benzene by

0.40K. The freezing point depression constant of benzene is 5.12 K kg/mol. Find the molar mass of the solute.​

Answer 1

Explanation:

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
