WebDiluting a solution by adding more solvent Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. WebAccording to the definition of molarity, the amount of moles of solute ( n) in a solution is equal to the product of the solution’s molarity (M) and its volume in liters (L): n = M × L. Expressions like these may be written for a solution before and after it is diluted: n1 = M 1 × L 1. n2 = M 2 × L 2.
