Answer:
[tex]n = 6.634\times 10^{23}\,atoms[/tex]
Explanation:
The total amount of atoms is found by multiplying Avogradro's Number and the number of moles:
[tex]n = \left(6.022\times 10^{23}\,\frac{atoms}{mol} \right)\cdot \left(\frac{70\,g}{63.546\,\frac{g}{mol} } \right)[/tex]
[tex]n = 6.634\times 10^{23}\,atoms[/tex]
