Membrane impermeable?

Question

4. If a 10% sucrose solution is separated from a 20% sucrose solution by a membrane impermeable to sucrose, in which direction will net movement of water occur?

A) From the 10% sucrose solution to the 20% sucrose solution

B) From the 20% sucrose solution to the 10% sucrose solution

C) There will be no net movement of water in this case.

D) A and B

E) None of the above

plz help sooooon

Answer 1

A) From the 10% sucrose solution to the 20% sucrose solution --->

through osmosis, the water will go to the area with the lowest percentage of water. the 10% sucrose solution has 90% water and the 20% solution has 80% water, so the water will go to from the 10% sucrose solution to the 20% sucrose solution

Answer 2

the membrane is impermiable to sucrose wich means that the water would move.

water (and air) like moving from high-pressure areas to low pressure areas so the water would move from the %20 to the %10

so B I would think

Answer 3

C

Answer 4

A.

Water moves from areas of lower solute concentration to higher solute concentration (or higher water concentration to lower water concentration, depending on how you look at it).  Because there is more solute (and less water) on the 20% sucrose side, water will flow from the 10% side to the 20% side.
