a flask contains two compartments (A and B) with equal volumes of solution separated by a semipermeable membrane. compartment a is filled with 2.0 M NaCl and B is filled with 2.0M glucose. What happens to the volume of the compartments over time? Briefly explain your reasoning
One NaCl has one Na+ particle and one Cl- particle, that is total two particles per one NaCl. So in compartment A 2.0 M NaCl actually has 2.0 M Na+ and 2.0M Cl-, that is total of 2.0+2.0 = 4.0 M solute particles.
But one glucose has only one solute particle. It can't split like NaCl. Thus compartment B has only 2.0 M concentration of solute particles.
Now the semipermiable membrane allows movement of only solvent water molecules across it, which move from a region of high solvent concentration (low solute concentration), that is compartment B, to a region of low solvent concentration ( high solute concentration) that is compartment A.
Hence over time volume of compartment A increases and that of compartment B decreases.
Comment if still any doubt.

4.40 A rigid, insulated tank consists of two compartments of equal volume separated by a valve. Initially, one compartment contains air at a pressure of 750 kPa and a temperature of 50°C, while the second compartment is completely empty. The valve is opened and it remains open until the two compartments reach pressure and temperature equilibrium. Determine the final pressure and temperature of the air, assuming each compartment has a volume of 0.65 m'.

A system is given by two compartments separated by a thin
membrane, and solute moves from one compartment to the other by
diffusion. The volume of compartment 1 is 0.03 cm^3 and compartment
2 is 0.01 cm^3. Suppose 50 M of solute is dumped into compartment
2, and the concentration response for compartment 1 is c1(t)=
