Frequently asked questions
What is C1V1 = C2V2?
The amount of substance does not change when you dilute: the stock concentration times the stock volume equals the final concentration times the final volume.
Can I mix units?
Yes, as long as both concentrations are the same kind: both molar, both percent, both mass per volume, or both X.
