Elanso [62]

Answer:

n = 6.634\times 10^{23}\,atoms

Explanation:

The total amount of atoms is found by multiplying Avogradro's Number and the number of moles:

n = \left(6.022\times 10^{23}\,\frac{atoms}{mol} \right)\cdot \left(\frac{70\,g}{63.546\,\frac{g}{mol} } \right)

n = 6.634\times 10^{23}\,atoms
