A sample of silicon has three naturally occurring isotopes: Si-28 (mass 28.0 amut); Si-29 (mass 29.0 amu) and Si-30 (mass = 30.0 amu). If the average atomic mass of silicon is 28.1 amu, which isotope is the most abundant? Select one O a. Si-30 â b. Si-28 O c. Si-29 O d. All isotopes have the same natural abundance.
