Question

the following question refers to the graph below, which illustrates the percent change in the mass of pieces of plant tissue placed in solutions of different molarities. the approximate molarity of the solution in which the mass of the plant pieces would not change is

Explanation:

Step1: Identify the key - point on the graph

The mass of the plant pieces does not change when the percent change in mass is 0.

Step2: Find the corresponding molarity

Locate the point where the percent - change in mass is 0 on the graph. Then, find the corresponding molarity on the x - axis. By observing the graph, when the percent change in mass is 0, the approximate molarity is 0.3M.

Answer:

0.3M
