p. 31 Molarity By Dilution (mixing with water. a concentrated solvent) Acids are usually acquired from chemical supply houses in concentrated form. These acids are diluted to the desired concentration by adding water. Since moles of acid before dilution = moles of acid after dilution, and moles of acid : CV then, C1 X V1 = C2 X V2.

molarity vs concentration

Molarity - Quia
Molarity, M. Molarity is a means of representing a solution’s concentration. In other words, it expresses how much dissolved solute can be expected from a given volume of solution. The . molar concentration or molarity, M, of a solution is used to indicate the number of moles of solute per liter of solution:
