14. There аre twо isоtоpes of helium: helium-3 аnd helium-4. 3He is proposed to be а safer nuclear fuel compared to uranium and plutonium. It has been suggested that the moon could be mined for helium-3. (WCSU26.[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?
