Molarity Calculator

n = m / M, c = n / V

Relate mass, amount of substance, molecular weight, volume and molar concentration. Solve for any one of them.

Inputs

g/mol

Result

1 mol

Calculation

  1. Amount of substance

    n = m / M

    n = 58.44 g / 58.44 g/mol

    n = 1 mol

Inputs

Mass
58.44 g
Molecular weight
58.44 g/mol
Volume
1 L

How the quantities relate

  1. Mass (m)

    58.44 g

    Weighed solute

  2. Mol. weight (M)

    58.44 g/mol

    n = m / M

  3. Amount (n)

    1 mol

    Moles of solute

  4. Volume (V)

    1 L

    Solution volume

  5. Concentration (c)

    1 mol/L

    c = n / V

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.

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