App description

Mass molar concentration

The amount of a substance of a solute B in the solution divided by the mass of the solvent is called the mass molar concentration of the solute. The unit is mol/kg, and the symbol is mB.

Formula

\(mB=n(solute)/m(solvent)\)

\(mass fraction of solute = \frac {solute}{solute + container} \times 100%\)

Usage example

Solute mass: 5 grams

Molar mass of solute: 10 g/mol

Solvent mass： 15 grams
