FAQs
1.What is the difference between C₁V₁ = C₂V₂ and M₁V₁ = M₂V₂?
+They are the same equation; M (molarity) is a common symbol for concentration. The formula works for any concentration unit as long as you use the same unit on both sides.
2.Can I use this for serial dilutions?
+Yes – for serial dilutions, you can apply the equation repeatedly. For example, to find the concentration after two steps, you would use the output of the first step as the new C₁ for the second step.
3.Why is the result for volume given in liters when I entered milliliters?
+The calculator converts all volumes to liters for the calculation and returns the result in liters for consistency. If you prefer milliliters, simply multiply by 1000.
