MASS ÷ VOLUME

For laboratory calculations only. This tool calculates mass, volume and concentration. It does not provide personal dosing, injection, administration or product-specific preparation instructions.

Calculation methods & assumptions

Concentration is compound mass divided by the final measured solution volume. 1 mg = 1,000 µg and 1 mL = 1,000 µL.

Dilution uses C₁V₁ = C₂V₂. The stock solution volume is the target concentration multiplied by the final volume, divided by the stock concentration. Diluent volume is the final volume minus the stock volume.

These arithmetic calculations assume complete dissolution, additive volumes and no material loss. They do not establish solubility, stability, sterility or suitability for a particular experiment.
