13. A dialysis bag is filled with distilled water and then placed in a sucrose solution. The bag is
permeable to sucrose, not water. The bag's initial mass is 20g, and its final mass is 28g. Which of
these statements best explains why the dialysis bag increased in mass?
A. Because the bag was placed in a solution with a higher sucrose concentration than that of the
bag, the semi permeable membrane allowed for sucrose to diffuse into the bag.
B. Because the bag was placed in a solution with a lower sucrose concentration than that of the
bag, the non permeable membrane did not allow for sucrose to diffuse into the bag.
C. Because the bag was placed in a solution with a higher water concentration than that of the
bag, the semi permeable membrane allowed for sucrose to diffuse out of the bag.
D. Because the bag was placed in a solution with the same sucrose concentration as the bag, the
semi permeable membrane allowed for sucrose to diffuse out of the bag,
