Dilution Formula
This calculator used the following formula to calculate the volume that needs to be added.
M1V1 = M2V2
- Where M1 is initial molarity
- V1 is the initial volume
- M2 is the final molarity
- V2 is the final volume
Dilution Defintion
Dilution is the process of a substance, typically a liquid, becoming less prevalent relative to other substances on the same solution.
How to calculate dilution?
How to calculate a dilution
- FIrst, determine the initial molarity and initial volume.
This is the initial molarity and volume of the solution at time = 0.
- Next, determine the final volume
This will be the final Volume of the solution after a certain time where another solution or base has been added to the solution.
- Calculate the final molarity
Molarity and Volume are directly proportional. With 3 variables the 4th can be calculated.
FAQ
A dilution is a term used in chemistry to describe the process of one substance becoming more or less prevalent within a given volume.
