QUESTION:
The average atomic mass of \({ }_{31}^{69} \mathrm{Ga}\) (68.9256 amu) and \({ }_{31}^{71} \mathrm{Ga}\) (70.9247 amu) is 69.72 amu. Calculate the natural abundances of the gallium isotopes.
ANSWER:Step 1 of 2
Here we have to calculate the natural abundances of the gallium isotopes.
Given:
The average atomic mass of the isotopes of Gallium is given as,
= 68.9256 amu
= 70.9247 amu
Average atomic mass = 69.72 amu
Let us consider the natural abundance of = X
Than the natural abundance of must be = 1-X
