Activity is defined as the product of rate constant and number of atoms. It is also defined as the rate of decay or expresses number of atoms decays in unit time.

Molar activity is defined as the product of activity and molar mass of the compound.

Number of moles is defined as the ratio of mass to the molar mass.

The mathematical expression is given by:

$\text{Number of moles = }\frac{\text{mass}}{\text{molar mass}}$
