1 The relative atomic mass, or atomic weight, of an element is the weighted average of the masses of the isotopes in the naturally occurring element relative to the mass of an atom of the carbon-12 isotope which is taken to be exactly 12.
Density is the mass per unit of volume of a substance. The density equation is: #Density# = #Mass/Volume#. To solve the equation for Mass, rearrange the equation by multiplying both sides times Volume in order to isolate Mass, then plug in your known values (Density and Volume). Then solve for Mass. #Mass# = #Density x Volume#.
