Atomic Mass Unit
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 g..
Atomic Mass Unit
An atom is a very minute particle and so the actual mass of an atom is extremely small. It is physically not possible to measure such small masses easily. In 1811, Avogadro suggested that atomic and molecular masses can be expressed on an..

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 m..
Relative Atomic Mass
Relative Atomic Mass - 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 i..

Experiments have determined that the mass of an atom is very small, ranging from 1.7x10 -24 g to about 4.0x10 -22 g. It is very difficult to accurately weigh a bunch of atoms, as they are extremely light, small, and invisible; they weigh too little ..
Modern definition of atomic mass unit
The mass of 1/12 part of 12 C isotope of carbon is equivalent to one atomic mass unit..
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 element..

It has tought me how to make my word more explained and This has tought me alot that i need to know , I am thankful -- Mark
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
Tutor Vista tutors are good at step by step explanation, which i really didn't find with any other website.
