Answer: 5.00 x 10^23 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of Iron = 6.02 x 10^23 atoms
0.83 moles of Iron = Z atoms
To get the value of Z, cross multiply:
Z atoms x 1mole = (6.02 x 10^23 x 0.83)
Z = 5.00 x 10^23 atoms
Thus, there are 5.00 x 10^23 atoms of iron.
