How do you find the mass of gallium 71?

1. where:
2. atomic mass = average atomic mass of the element.
3. f.a. = fractional abundance of the isotope.
4. To get f.a., we simply need to divide the given percent abundance by 100.
5. We’re given the following values:
6. Ga-69: Mass = 68.9256 amu f.a. = 0.6011.
7. Ga-71: Mass = 70.9247 amu f.a. = 0. 3989.
