The average atomic mass of the element is 204.40 amu

Average atomic mass and isotopic mass

  • The average atomic mass of an element is the average mass of the atom of that element calculated from the isotopic masses of the atoms of that element and their percentage abundances
  • Isotopic mass is the mass of each isotope of that element

Calculation of average atomic mass

Average atomic mass = sum of isotopic mass * abundance of each isotope

Average atomic mass = 202.99 * 29.524% + 70.476% * 204.99 amu.

Average atomic mass = 204.40 amu

Therefore,  the average atomic mass of the element is 204.40 amu
