Study Notes
Gallium Isotope Abundance
- Gallium's atomic mass is 69.723.
- Gallium has two naturally occurring isotopes.
- The weighted average atomic mass of gallium is calculated using the abundance of its isotopes.
- The equation representing the weighted average is 69.723 (100%) = 68.9256 (X %) + 70.9247 (Y %).
- Solving for X, the abundance of the lighter isotope (69 Ga), yields 60.11 %.
- The abundance of the heavier isotope (71 Ga) is 100% - 60.11% = 39.89 %.
