Question

What is the relative atomic mass of an element?

Answer 1

Relative atomic mass (R.A.M)

1. It is a ratio of the actual mass of atom with respect to the 1/12th of the mass of carbon -12 atom.

R.A.M $=\frac{\mathrm{Mass}\mathrm{of}1\mathrm{atom}\mathrm{of}\mathrm{an}\mathrm{element}}{{\displaystyle \frac{1}{12}}\times \mathrm{Mass}\mathrm{of}1\mathrm{atom}\mathrm{of}\mathrm{C}-12}$

2. The relative atomic mass of an element is the average value for the isotopes of the element.

For example, relative atomic mass of carbon is 12.
