Lecture 46: Molarity 15.5 Solution Composition: Molarity A solution is described in terms of concentration. The most common expression of concentration is molarity (M) Molarity is the number of moles of solute per volume of a solution in liters. M = molarity = moles/volume = A one molar solution (1.0 M) contains 1.0 mol of solute per liter of solution. Sometimes we can rearrange the above equation to solve for the number of moles.

Unformatted text preview: M * V = mol 15.6 Dilution Stock solutions are purchased or prepared concentrated solutions. Adding solvent to a solution is called dilution; that is, the moles of solute do not change in dilutions. M 1 * V 1 = mole of solute = M 2 * V 2 Moles of solute Liters of solution...
