One mole of 1 dollar bills joined end to end would encircle the earth 2.34 * 10¹⁵ times.
The length of a 1 dollar bill is 15.6 cm = 0.156 m
One mole of 1 dollar bills will contain 6.02 * 10²³ bills.
Length of 1 mole of 1 dollar bills = 0.156 * 6.02 * 10²³
Length of 1 mole of 1 dollar bills = 9.39 * 10²² m
Length of 1 mole of 1 dollar bills = 9.39 * 10¹⁹ km
Circumference of the earth = 40075 km
Number of times 1 mole of 1 dollar bills will circle the earth = 9.39 * 10¹⁹ km/40075 km
Number of times 1 mole of 1 dollar bills will circle the earth = 2.34 * 10¹⁵ times.
Therefore, one mole of 1 dollar bills joined end to end would encircle the earth 2.34 * 10¹⁵ times.
