I was reading through the section on Molarity (G). The textbook stated something about "we use molarity of solute, not molarity of solution." I do not really understand this because I thought molarity was the same for both. Can someone help explain the difference?

The molar concentration is called the "molarity" and its formally known as the "amount of substance concentration." We use moles of solute and the volume of the solution to find the concentration, or molarity of a solution. Moles of solute are used to find the molarity of a solution.

Molarity is the moles of solute per volume of solution. I think the textbook is trying to say that with molarity we are concerned more with how much solute and solution there is, but not how much solvent there is.

The volume is measured after you add the solute in the solvent and I think when they said molarity the want to know the concentration of the solute that you have within your solution. For example, it would ask you what is the concentration of NaCl is in a solution, they want to know how heavily concentrated the NaCl is in the solution not, for example, how concentrated the solution is by the solvent.
