For this problem, assume that water consistsonly of the most abundant isotopes of oxygen ( 16 O and 18 O ). Theatomic mass for 16 O is 15.9949146 u, and the atomic mass for 18 O is 17.99916 10 u. (a) A standard seawater sample contains 0.1995% 18 O . Calculate the atomic weight of oxygen in seawater, and report youranswer to five decimal places. (b) A polar ice core sample contains 0.1971% 18 O . Calculate theatomic weight of oxygen in polar ice, and report your answerto five decimal places.
