Question

Which of the following will cause the molarity of a solution to increase?

a) Evaporation of solvent
b) Addition of solvent
c) Addition of solute
d) More than one of these will increase the molarity of a solution.

Answer 1

The addition of solute will cause the molarity of a solution to increase.

Step-by-step explanation:

The addition of solute (c) will cause the molarity of a solution to increase. When a solute is added to a solvent, it increases the number of moles of solute in the solution without changing the volume of the solvent. This results in a higher concentration of the solute particles in the solution, increasing the molarity of the solution.
