Atomic and Molecular Masses
It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a relative ..

Mendeleev's periodic table helped in correcting the atomic masses of some of the elements, based on their positions in the periodic table. For example, atomic mass of beryllium was corrected from 13.5 to 9.0. Atomic masses of indium, gold..

The mass of 1/12 th 12 C isotope of carbon is now the standard used for defining one atomic mass unit (a.m.u). It is equal to 1.66 x 10 -24..
Gram Atomic Mass (GAM)
The atomic mass of an element expressed in grams is called the gram atomic mass of an element. It is also called gram atom. Example: The gram atoms present in 46 grams of sodi..

An atom or a molecule is a very minute particle; the actual mass of an atom is extremely small. The mass of atoms extends from 1.67 x 10 - 2 4 g (hydrogen) to 4.0 x 10 - 2 2 g only. It is physically not possible to measure such small and ligh..
