3. Which among the following is temperature dependent?a. Mass %b. Mole fractionc. Molarityd. Molality

The temperature dependent among the following is c. Molarity.

Here's why:

a. Mass %: This is the mass of the solute divided by the total mass of the solution, multiplied by 100%. It is not affected by temperature.

b. Mole fraction: This is the ratio of the number of moles of a component to the total number of moles of all components in the mixture. It is also not affected by temperature.

c. Molarity: This is the number of moles of solute per liter of solution. It is temperature dependent because the volume of the solution can change with temperature.

d. Molality: This is the number of moles of solute per kilogram of solvent. It is not affected by temperature because the mass of the solvent does not change with temperature.
