Question

' x ' g of NaCl is added to water in a beaker with a lid. The temperature of the system is raised from $1^{\circ} C$ to $2 5^{\circ} C$ . Which out of the following plots, is best suited for the change in the molarity (M) of the solution with respect to temperature?
[Consider the solubility of NaCl remains unchanged over the temperature range]
