Atomic Mass Unit Scale
The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale. Atomic masses are not expressed as whole numbers because natural elements are mixtures of two or more i..
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..
Mass
The SI unit is kilogram. 1 kg is defined as the mass of a platinum-iridium cylinder kept at the International Bureau of W and M at Sevres, France, established in 1887. The atomic structure of mass is yet to be develop..
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..
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 is physically not possible to measure such small and..
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..

This tutors are better than my instructors at school, learned alot from this in these past few sessions, thank you Tutor Vista -Abrielle
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
My grades increased drastically with Tutor Vista and I'll definitely recommend this to all students who want to do better in their school. Not only do we learn, we also have fun!
