The solution dilution calculator will calculate for you how to dilute a stock solution of known concentration to obtain an arbitrary volume of a diluted solution. Read this article to learn how to use this tool correctly and what units to choose. And if you're interested in chemistry, give our half life calculator a look!
The main objective of this this concentration calculator is determining how to dilute a stock solution. Imagine you have a concentrated solution of hydrochloric acid. You can use this calculator to determine how much of it you need if you want to obtain 200 mL of a diluted solution with concentration 20 mM.
You can easily calculate this value, using the following dilution formula:
m₁ * V₁ = m₂ * V₂
Note that this equation is not equivalent to the proportion formula.
You probably know that the units of volume are either cubed units of length (for example cubic meters, cubic millimeters etc.) or liters. We will just remind you that 1 liter is equal to 1 cubic decimeter.
What about the units of concentration, then? You can either use molar or mass concentration. Our solution dilution calculator uses molar concentration, but we will teach you how to recalculate the units of mass concentration, too.
If you want to find the mass concentration of your solution, you need to multiply the molar concentration by the molar mass of the substance M (expressed in kg/mol):
ρ = c * M
You can also find it using our molarity calculator.
1 * V₁ = 20 * 10^(-3) * 0.5
V₁ = 0.01 = 10 mL
