Question

1. identify where on your graph you expect to find the molarity at which a nacl solution would be isotonic with the potato cells.

options: x - intercept, the minimum point, y - intercept, the slope of the trend line

Explanation:

An isotonic solution has the same solute concentration as the potato cells, so there will be no net movement of water, meaning the % change in mass is 0. On the graph, this occurs where the trend line crosses the x-axis (y=0), which is the x-intercept.

Answer:

X-intercept
