Atomic Mass
. While the mass of one atom of hydrogen is considered as 1 atomic mass unit, hydrogen gas in its natural state has 3 isotopes of atomic mass 1, 2 and 3 respectively. Thus average mass works out to be 1.008 a.m.u rather..
Atomic Mass of Elements
Experimentally it is determined that the mass of an atom is very small ranging from 1.7 x 10 - 2 4 g to about 4.0 x 10 - 2 2 g. These small masses are terribly impractical to work with. Thus, it became necessary to reduce the atomic masses into simp..

Atomic Mass of an Element or Relative Atomic Mass
The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to the mass of one carbon-12 atom. Thus,Relative atomic mass (RAM) of an element is ..

Atomic Mass - 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 mole..

Atomic masses of many elements are in fractions not in whole number..
Drawback of using hydrogen as atomic mass unit
Hydrogen gas in its natural state has 3 isotopes of atomic mass 1, 2 and 3 respectively. Thus average mass works out to be 1.008 a.m.u rather than 1 a.m.u. This in turn complicates the atomic masses of all other elements..
Calculation of Molecular Mass
Molecular mass is equal to sum of the atomic masses of all atoms present in one molecule of the substance.Example: H 2 OMass of H atom = 1Mass of 2H atoms = 2Mass of O atom = 16Molecular mass = 2 + 1..
Relation Between Atomic Number and Atomic Mass
Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element..
