About this calculator

Amount of substance is mass divided by molecular weight (n = m / M). Molar concentration is amount divided by volume (c = n / V). Given any sufficient combination of values, the remaining quantity follows directly.

Only the fields needed for the selected target are required. If a required value is missing, the calculator says which one instead of assuming a default.

LabCalc is provided as a calculation aid. Users remain responsible for verifying calculations, units, chemical compatibility, experimental procedures and applicable safety requirements before laboratory use.
