How do you find the mass of gallium 71?
- where:
- atomic mass = average atomic mass of the element.
- f.a. = fractional abundance of the isotope.
- To get f.a., we simply need to divide the given percent abundance by 100.
- We’re given the following values:
- Ga-69: Mass = 68.9256 amu f.a. = 0.6011.
- Ga-71: Mass = 70.9247 amu f.a. = 0. 3989.
