Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article.

Isotopes In this paper too, radium is taken to mean 226Ra, while other isotopes are a Atomic weights for Ac, Pa and Np are based on the masses of nuclides that occur Ra-226. 1600 y.

Now, we've got a radium-226 atom. That 226 means that its mass number is equal to 226; elements occur, in nature or in lab, in many different forms, with of course the same atomic number but varying amounts of neutrons, resulting in varying mass numbers. These different 'versions' of an element are known as isotopes. The atomic mass number of Radium is `A=226`, its half life is `1622` years. What is the activity of `1g` Radium ?
