How is a mole related to concentration?

Question

A. The saturation point of a solution is, measured in moles
B. The number of particles of solute in a solution is measured in moles
C. The mass of the solute in a solution is measured in moles
D. The volume of particles of solute in a solution is measured in moles

Answer 1

The correct answer is:

B. The number of particles of solute in a solution is measured in moles.

In chemistry, a mole is a unit that quantifies the amount of substance. Concentration refers to the amount of solute in a given volume of solution, and it is often expressed in moles per liter (mol/L), commonly known as molarity. Therefore, the mole is directly related to the quantity of solute present in a solution.
