Question

1. look at your data. consider your data points and the curve fit line. identify the molarity of a nacl solution in which the celery cells would be in an isotonic environment. m the answer to this question depends on your answers to previous questions. submit answer × 1 / ∞ submissions used score: 0/1 comments: can you find a nacl solution molarity in which the cells do not change mass. this is will be where your curve fit crosses the x - axis or your data point is closest to 0.

Explanation:

Step1: Define isotonic condition

An isotonic solution has 0% mass change for celery cells, so find where the linear fit line intersects $\% \text{Change in Mass} = 0$.

Step2: Read x-axis value at intersection

From the graph, the linear fit crosses $\% \text{Change in Mass} = 0$ at a molarity of 0.2 M.

Answer:

0.2 M
