WebJan 31, 2024 · Molarity and parts per million (ppm) are two units of measurement used to describe the concentration of a chemical solution. One mole is equivalent to the molecular or atomic mass of the solute. Parts per million, of course, refers to the number of molecules of solute per million parts of a solution. WebAccording to the definition of molarity, the molar amount of solute in a solution is equal to the product of the solution’s molarity and its volume in liters: n =M L n = M L. Expressions like these may be written for a solution before and after it is diluted: n1 = M 1L1 n 1 = M 1 L 1. n2 = M 2L2 n 2 = M 2 L 2.
