There are two naturally occurring isotopes of a hypothetical element, E. The atomic mass of one isotope, 68E, is 67.9827 amu, and the mass of the other isotope, 63E, is 62.9774 amu. The average atomic mass of element E is 63.5471. Which statement(s) about element E is/are true? A. The two isotopes have the same abundance. B. 68E is the more abundant isotope. C. 63E is the more abundant isotope. D. Both isotopes contribute equally to the average atomic mass of element E. E. 63E contributes more to the average atomic mass of element E.
