The molar concentration or number of molecules per unit volume (choose as desired from the menu) is calculated from the mass concentration by use of the molecular weight and object density.

Arrhenius equation

Two interconverting species A and B have an equilibrium ratio that depends on their difference in energy and the temperature, according to the equation ΔG=RT*ln(k), where k is the equilibrium constant. This can be derived from the Arrhenius equation calculator (temp-rate dependence) for the forward and backward reactions.

Solution dilution

The solution concentration (both molarity and mass-volume fraction) is calculated by dividing the amount of substance by the volume of the solution. For molar concentrations, the molecular weight is also required in order to calculate the number of molecules in the given mass of solute.
