When the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises. Based on this information, what can be said about these two solutions? View Available Hint(s) When the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises. Based on this information, what can be said about these two solutions? The unknown solution had the lower concentration. The unknown solution had the higher concentration. The two solutions have the same concentration.

The correct answer to the question is

The unknown solution had a higher concentration of solutes

Explanation:

The process of the movement of the molecules of the solvent across the semipermeable membrane is known as osmosis

Osmosis is the passive transport of a solvent such as water through a selectively permeable  membrane in a direction from a region of low solute concentration to a higher concentration region so as to equalize the concentration of the solute on both sides of the membrane

you need to have a picture of the atom that way we can answer it

yes the answer is total mass in unchanged   : )
