WebOn the basis of the abundance of isotopes, we can calculate the isotopic mass and average atomic mass of an element. The average mass of element E can be expressed as: m ( E) = ∑ n = 1 m ( I n) × p ( I n) For example, the mass and abundance of isotopes of Boron are given below. The average mass of Boron can be calculated as:
WebThe relative abundance of Deutrium (1 proton, 1 neutron) is so small that it is barely accounted for when calculating the average atomic mass. So the mass of a proton is around 1.008 amu, not 1. Following this logic, the carbon-12 atom's atomic mass should actually be 12.09 amu; however, the mass is exactly 12 amu.
