2. If solution A were separated by a selectively permeable membrane from solution B and A demonstrates greater osmotic pressure, what can u conclude regarding the solute concentration in A?
Answer: The solute concentration is also higher in solution A because the osmotic pressure is directly proportional to solute concentration.
in which direction would there be a net movement of water?
The movement of water will be from solution B to A because water flows from a solution of lower solute concentration to higher solute concentration.

3. In an osmometer, no net movement of water molecules into the thistle tube occurs when the hydrostatic pressure of the tube equals its osmotic pressure. how would you describe this condition?
Answer: hydrostatic pressure is the fluid pressure of the solution. An opposing pressure can prevent the flow of water into the solution. hence, when the hydrostatic pressure is equal to the osmotic pressure it opposes the osmotic pressure of the solution so that no net movement of water molecules occurs.
