For the first five problems, you need to use the equation that says that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. Since only the volume changes in this solution, this same number of moles will be in the second solution. Quantitative units of concentration include molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion.

Also Remember That The Volumes In Milliliters Can Be Converted To Liters (See Table To The Right).
