Boron has two naturally occurring isotopes: B-10 with mass 10.013 amu and a natural abundance of 19.78% and B-11 with mass 11.009 amu and a natural abundance of 80.22%. Calculate the atomic mass of boron.
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...
