Concept introduction:
Average atomic mass is the ratio of mass of an atom of the element to mass of 1 hydrogen atom or 1/12 th of a C12 atom or 1/16 th of a O16 atom.

Answer to Problem 1E
Average atomic mass is calculated by considering all the
The unit is equal to that of atomic mass or amu.
Explanation of Solution
Average atomic mass is calculated in the following way. Example of Cl atom is taken to explain the caculation.
Cl has two isotopes Cl35 and Cl 37. Abundances of 1st one is 75 % and 2nd one is 25 %.
Average atomic mass can be calculated as follows:
