Suppose you had 1.00 moles of pennies (each penny has a thickness of 0.059 inches) and you stacked them one on top of each other to make a very tall pile. You set off from the bottom of the pile in a space craft that can travel at the speed of light (3.00 x 10^8 m/s). How long, in years, will it take you to reach the top of the pile of pennies? Show all work.
