Answer:
719
Explanation:
Conversion
1 picometer (pm) is equivalent to [tex]1 × 10^{-12}[/tex] meter
1 micrometer is equivalent to [tex]1 × 10^{-6}[/tex] meter
To find the number of layers, we divide the overal leaf thickness by the thickness of one atom hence dividing tex]0.125 × 10^{-6}[/tex] meter by [tex]174 × 10^{-12}[/tex] meter we get that the number of sheets will be as follows
[tex]\frac {0.125× 10^{-6}}{174\times 10^{-12}}=718.3908045\approx 719[/tex]
Therefore, they are approximately 719 sheets
