In lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell". The balloon is filled with a solution of 20% sucrose and 80% water and is immersed in a beaker containing a solution of 40% sucrose and 60% water. Which of the folloing will occur?

Question

A. water will enter the balloon
B. water will leave the balloon
C. sucrose will enter the balloon
D. sucrose will leave the balloon
E. none of the choices will occur

Answer 1

B
The question said that the balloon was impermeable to sucrose, therefore sucrose cannot enter or leave the balloon.

There is a higher concentration of water inside the balloon, so water will flow out in an attempt to balance both sides.
