Molarity revisited
Sometimes, you may need to determine the number of moles of solute dissolved in a given volume of solution. You can do this if the molarity of the solution is known. For example, how many moles are in 2.00 L of 2.5M lithium chloride (LiCl)? Rearrange the formula for molarity to solve for the number of moles.
Moles of solute = molarity (M) × liters of solution (V)
Thus 2.00 L of 2.5 M lithium chloride solution contains 5.0 mol LiCl.
