Mass/Volume Dilution Calculator: calculate required solute mass for target concentration and final volume in common lab units such as mg/mL, µg/mL, and g/L.
Use this mass/volume dilution calculator to calculate the required solute mass, stock concentration, target concentration, or final volume when preparing solutions in g/L, mg/mL, and µg/mL. It is useful for chemistry, lab work, buffer preparation, and routine solution making.
The calculator applies the C1V1 = C2V2 dilution relationship, supports common mass and volume units, and allows reverse calculation when one value is unknown. It also shows the solvent volume to add using V = V2 - V1.
Dilution formulas
$$C_{1}V_{1} = C_{2}V_{2}$$ $$V = V_{2} - V_{1}$$
Frequently asked questions about mass/volume dilution
This calculator uses the standard dilution formula C1V1 = C2V2, where C1 and V1 are the stock concentration and stock volume, while C2 and V2 are the target concentration and final volume.
Enter the known values for C1, V1, C2, and V2. The calculator automatically solves for the missing quantity needed to prepare the solution.
You can work with units such as g/L, mg/mL, and µg/mL, together with common volume units. The main requirement is to keep the units consistent throughout the calculation.
Once the required stock solution volume is known, the added solvent volume is calculated as V = V2 - V1. This tells you how much water or other solvent must be added to reach the final volume.
Yes. If one of the main values in C1V1 = C2V2 is unknown, the calculator can solve for it. This is useful for reverse lab calculations and checking prepared solutions.
