Answer:
2.439 x 10E24 atoms
Explanation:
from
N=n x NA where
N- number of atoms
n-number of moles and NA is the avogadro's number
(exact weight of isotope #1) (abundance of isotope #1) + (exact weight of isotope #2) (abundance of isotope #2) = average atomic weight of the element(68.72*61.29) + (39.71*70.92) = 4211.84 + 2816.237028.07/100= 70.28
70.28 is the atomic mass of Gallium for the location
