An element has two different isotopes: one that weighs 65 amu and another that weighs 67 amu. If the average atomic mass of all the isotopes is 65.5 amu, what can be said about the relative abundance of the isotopes? a. The isotope with the mass of 66.5 is more abundant than the isotope with the mass of 65 b. The isotope with the mass of 67 is more abundant than the isotope with the mass of 65 c. The...

Most elements occur naturally as a mix of different isotopes. An element's atomic mass is the weighted average of the isotope masses. In other words, it is an average that takes into account the percentage of each isotope. For example, the two naturally occurring isotopes of boron are given here The atomic mass of boron is calculated as follows: (10.0 times 0.199) + (11.0 times 0.801) = 10.8 amu Because the heavier isotope is more abundant the atomic mass a...
