Gallium has two naturally occuring isotopes: Ga-69 with a mass of 68.9256 amu and a natural abundance of 60.11% and Ga-71. Use the atomic mass of gallium listed in the periodic table to determine the mass of Ga-71. How do I figure out this isotopic problem without the amu of gallium 71. I know how to get the abundance but not the amu from this slim figures.
