Question:

Germanium has three major naturally occurring isotopes: ⁷⁰Ge (69.92425 u, 20.85%), ⁷²Ge (71.92208 u, 27.54%), ⁷⁴Ge (73.92118 u, 36.29%). There are also two minor isotopes: ⁷³Ge (72.92346 u) and ⁷⁶Ge (75.92140 u). Calculate the percent isotopic abundances of the two minor isotopes. Comment on the precision of these calculations.
