The element Europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 amu, and 153Eu has a mass of 152.9209 amu. The average atomic mass of europium is 151.96 amu. Calculate the relative abundance of the two europium isotopes.© BrainMass Inc. brainmass.com March 4, 2021, 5:43 pm ad1c9bdddf
If the ratio of 151-Eu = x then the ratio of 153-Eu will be 1 - x since they ...
This solution calculated the relative abundance of an element based on atomic masses and average atomic mass.
