Question

What is the formula for calculating the relative atomic mass of an atom?

Answer 1

Hi friend

------------------------------------------------------

RELATIVE ATOMIC MASS =

The average mass of one atom
__________________________
1/2 x The mass of carbon-12 atom

Answer 2

Hi
_______________________________________________________________

One relative atomic mass or formula= 1/2 x the mass of carbon-12 atom

For calculating the relative atomic mass of a molecule you should know the atomic mass of the constituent elements of the molecule concerned.

Let's assume you have to find the relative atomic mass of water (H²O).

Atomic mass of Hydrogen (w)= 1

Atomic mass of Oxygen (w)= 16

Number of H atoms in H²O (n)=2

Weight of H in H²O (nw)= 2x1= 2

Number of O atoms in H²O (n)=1

Weight of O in H²O= 1x16 (nw)=16

Relative atomic mass= 16+1=17
