Now consider the isotope problem. You have already learned about isotopes so you know that hydrogen has three isotopes and oxygen has three isotopes (O-16, O-17, and O-18). Each isotope of an element occurs with a percent abundance (PA).

Since you don't know the percent abundance of either isotope, you will have to express that unknown of one isotope in relation to another. (mass of first isotope)(abundance of first isotope)+(mass of second isotope)(abundance of second isotope)=average atomic mass;
