Question

HOW CAN I CALCULATE RELATIVE ATOMIC MASS? AVERAGE ATOMIC MASS?

Answer 1

Explanation:

Relative atomic mass =

$\frac{mass \: of \: a \: single \: molecule}{ \frac{1}{12}th \: mass \:of \: carbon \: - 12 \: atom }$

The relative atomic mass of an element is the average mass of its atom compared to 1/12th the mass of carbon -12 atom.

Average Atomic mass=

it is calculated by summing the masses of elements isotope each multiplied by its natural abundance on earth.
