Solution: 12/6.022*10^23 = 1.9927*10^-23. We know that carbon 12 has a mass of 12 a.m.u and 1 amu =1.66*10^-24 grams.
atomic mass of 62.9298 amu and an abundance of 69.09%. The other isotope, 65Cu, has an abundance of 30.91%. The average atomic mass between these two isotopes is 63.546 amu. Calculate the actual atomic mass of 65Cu. .6909 X 62.9298 = 43.47819 .3091 X _____=_____ 63.546
