An experiment was performed in which potato cores were placed in sucrose solutions of varying molarity. After time had passed, the percent change in mass of the potato cores was determined. The results of the experiment are shown in the graph. A line graph shows sucrose molarity from 0 to 1 Upper M on the x axis and Percent change in mass from negative 30 to positive 30 on the y axis. Line starts at (0, 20) to (.2, 10), to (.4, negative 5), to (.6, negative 17), to (.8, negative 25) to (1, negative 30).

Which of the following solutions was hypertonic to the potato? Why?

0.2 M because the potato core increased in mass, meaning water moved into the solution from the potato
0.2 M because the potato core increased in mass, meaning water moved into the potato from the solution
0.6 M because the potato core decreased in mass, meaning water moved into the solution from the potato
0.6 M because the potato core decreased in mass, meaning water moved into the potato from the solution
