Dilution Formula, general chemistry
Dilution is a common type of problems given to students in the concentration chapter of their chemistry class. To dilute something means to add water to the solution, which will in turn decrease the concentration.
The formula for dilution is M1V1= M2V2
where M1= Molarity 1
V1 = Volume 1
M2 = Final Molarity
V2= Final Volume
Note, that for this formula your volume can be in any units as long as it is consistent on both sides.
