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 kilometers) ? [For comparison, the sun is about 150 million km from Earth and the nearest star (Proxima Centauri) is about 40 trillion km from Earth.]

Answer:my

The height of the stack will be 9.15*10^20_m

Or 9.15*10^17_Km

Which is 6 billion times more more than the distance to the sun

Or 22.9 million times further than the star Proxima Centauri

Step-by-step explanation:

Given

Avogadro's number = 6.02*10^23 particles

And the thickness of a penny = 1.52_mm

The height of the stack will be

1.52 * 6.02 * 10^23 = 9.15*10^23_mm 9.15*10^20_m
