Question

READ: A student cut three identical slices from a potato. She determined the mass
of each slice. She then placed them in labeled beakers and added a different solution
to each beaker. After 30 minutes, she removed each potato slice from its solution,
removed the excess liquid with a paper towel, and determined the mass of each slice.
The change in mass was calculated and the results are shown in the data table
below.

Answer 1

This was due to osmosis which is is the movement of molecules from a high concentration to a lower concentration

Beaker one became more concentrated since it had a lower concentration causing it to gain mass

Beaker two and 3 became less concentration sink the salt solution moved out of the potato causing it to have a lower concentration and loose mass due to the loss of solution in the potato
