To calculate the atomic mass of gallium using weighted average mass method. Concept introduction: Atoms of same element having same atomic number , but different mass number are called isotopes. They contain equal number of electrons and protons, but the number of neutrons is different in their nuclei. The atomic mass of such atom is the average mass of all isotopes. Given: Mass of Ga 69 = 68 . 93 amu and percentage amount = 60.11 % Mass of Ga 71 = 7 0. 92 amu and percentage amount = 39.89 %
