Answer :
Based on the given graph, the molarity at which potato cores lose the most mass is the molarity of 1.0
What is molarity?
Molarity, M, is a unit of concentration commonly used in chemistry. It is defined as the number of moles of solute dissolved in one liter (L) of solution.
The formula to calculate molarity is:
Molarity (M) = Moles of Solute / Volume of Solution (in liters)
Molarity is used to express standard concentrations. For example, a 1 M (1 mol/L) solution of sodium chloride (NaCl) means that there is 1 mole of NaCl dissolved in every liter of the solution.

Final answer:
Potato cores lose most mass in a hypertonic solution and gain most mass in a hypotonic solution, which can be empirically found through osmotic experiments. The molarity at which the plant cells neither swell nor shrink can be used to determine the osmotic pressure of the cell contents by using freeze point depression.
Explanation:
To determine at what molarity potato cores lose the most mass, one would examine the point at which osmosis causes the potato cells to lose water to the surrounding solution due to a high concentration of solutes outside the cell (hypertonic solution). Conversely, potato cores gain the most mass at the molarity where the surrounding solution has a lower solute concentration than inside the cells (hypotonic solution), leading to water uptake. The exact molarity at which these events occur can be determined through an experiment involving the placement of potato cores in solutions with varying molarity and measuring the subsequent mass changes.
In an osmotic pressure calculation, the osmotic pressure inside plant cells can be determined from a given freeze point depression. As detailed in the question, if the contents of the plant cells are in osmotic equilibrium with the NaCl solution and molarity is equivalent to molality, then the osmotic pressure of the plant cells would be the same as the NaCl solution's osmotic pressure.
