A solution contains 0.050M FeSO₄ and 0.19M glucose. What is the total molarity of solute particles in the solution? (Glucose is a nonelectrolyte)

Solution A and B are separated by a semipermeable membrane. Solution A contains 0.1M glucose and 0.05M sucrose. Solution B contains 0.12M glucose. Does osmosis occur? If so, which direction does water flow, from solution A to solution B or from solution B to solution A?

What is the difference between dialysis and osmosis?

Two solutions are separated by a semipermeable membrane; Solution A contains 0.1M glucose and 0.05M sucrose. Solution B contains 0.05M glucose and 0.05M sucrose. The membrane allows both sucrose and glucose to pass through. Predict the direction of dialysis for each solute. Will osmosis occur? If so, which way will water flow?
