chemistry helppp please?

Question

a semipermeable membrane separates a 4%(m/) NaCl solution from a 2% (m/m) NaCl solution. INitially, the two solution levels are the same, but over time the levels become different.
a. which solution level will riseand which will drop?
b. which solution becomes more concentrated
c. in which direction, if any, is there a net flow of solvent
d. in which direction, if any, is there a net flow of solute

please show your workkkk

Answer 1

a) 4%(m/) NaCl solution level will rise and 2% (m/m) NaCl solution level will drop.
b) 2% (m/m) NaCl solution becomes more concentrated
c) From 2% (m/m) NaCl solution to 4%(m/) NaCl solution
d) None.
