Since molarity is defined as moles of solute per liters of solution, diluting a solution will result in a decrease in its concentration.


So, if the number of moles of solute must be constant in order for a dilution to be performed, you can use the molarity and volume of the target solution to figure out how many moles of solute must be present in the sample of stock solution you're diluting.
