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 kilom

Mashutka [201]

A penny is described as a coin having thickness of about 0.019 m as follows:

$Thickness of a penny = 0.019 m$

$Number of pennies stacked is equivalent to Avogadro number = 6.02 * 10^23 penny$

$Distance convered by number of pennies = 6.02 * 10^23 * 0.019 = 1.14 * 10^19 Km$

$Thus the stack of pennies extended upto 1.14 * 10^19 Km$
