14. There are two isotopes of helium: helium-3 and helium-4. 3He is proposed to be a safer nuclear fuel compared to uranium and plutonium. It has been suggested that the moon could be mined for helium-3. (WCSU25.[x], 9 points) Table 1: Isotopes of helium and abundance on the moon. Isotope Mass abundance 3He 3.016 amu ? 4He 4.003 amu 3.66% a. What is the percent abundance of helium-3 on the moon? b. What is the average atomic mass of helium on the moon? (show all work for full credit) c. Given the atomic mass of helium on the periodic table, what isotope is more abundant here on earth? Explain in a few words (no calculation).

15. Pepto-Bismol contains bismuth salicylate (C7H5BiO4) and is used to treat a variety of symptoms including nausea, heartburn, upset stomach, indigestion, and diarrhea. (WCSU25.[x], 9 points) a. Calculate the mass, in grams, of a single atom of bismuth (Bi), MW = 208.98 g/mol. b. Calculate the number of bismuth atoms in one dose of Pepto-Bismol that contains 303 mg of bismuth.
