I am supposed to find the percent abundancies of two isotopes. I am given the masses of both isotopes, along with the atomic mass. (This is a fictional element with only those two isotopes.) I am not given percentages for either isotope... how do I solve this?

  • Chemistry -

    Well, if the Percent of A is A, then the percent of B is 1-A (decimal percents.)

    Then
    avgatomicmass=massA*precentA + massB(1-percentA)
    solve for percent of A.
