A Chemistry student at Agora is calculating the average atomic mass of Potassium using the following data. Isotope K-39 K-41 Relative abundance 93.12 % 6.88% Their setup and calculation are. Mass (amu) 38.964 40.962 Atomic Mass 38.964 amu 40.962 amu Relative Abundance (% divide by 100) 0.0688 0.9312 = 2.681 38.144 40.823 amu = The student calculated the average atomic mass to be 40.823 amu but it is 39.098 amu on the periodic table.
