Part A

If you stacked Avogadro's number of pennies one on top of the other on Earth's surface, how far would the stack extend (in km)? [For comparison, the sun is about 150 million km from Earth and the nearest star (Proxima Centauri) is about 40 trillion km from Earth.]

Explanation / Answer

Avogadro number = 6.023 x 1023

Distance resulting from stacking Avogadro number of pennies each with a thickness of 1.0 mm = 6.023 x 1023 x 1.0 mm

= 6.023 x 1023 mm

= 6.023 x 1017 km
