The metal rhenium (Re) was predicted to exist by Dmitri Mendeleev but was not discovered until 1925. Rhenium is composed of two isotopes, Re-185 (mass 184.95 amu) and Re-187 (mass 186.96 amu). Given that the average atomic mass rhenium is 186.21 u, calculate the percent abundance of each of these isotopes. Show a full solution and round the final answer to 1 decimal place.
