Naturally occuring iodine has an atomic mass of 126.9045. A 12.3849 gram sample of naturally occurring iodine is acidentally contaminated with an additional 1.00070 grams of 129I, a synthetic radioisotope of iodine used in the treatment of certain tyroid glad diseases. The mass of 129I is 128.9050 amu. Find the apparent "atomic mass" of the contaminated iodine.
