You can answer these kinds of pressing questions by using the dilution equation, which relates concentration (C) and volume (V) between initial and final states: C 1 V 1 = C 2 V 2. You can use the dilution equation with any units of concentration, provided you use the same units throughout the calculation.

Solution Dilution Calculator | Sigma-Aldrich

In both dilution and concentration, the amount of solute stays the same. This gives us a way to calculate what the new solution volume must be for the desired concentration of solute. From the definition of molarity, molarity = moles of solute / liters of solution . we can solve for the number of moles of solute: moles of solute = (molarity)(liters of solution) A simpler way of writing this is ...
