Scale & Analogy Simulator — From Dozen to Mole
If you stacked 6.022 × 10²³ pennies (each 1.55 mm thick):
trips to the moon and back!
(Moon distance: 384,400 km)
If you lined up 6.022 × 10²³ atoms side by side (0.1 nm each):
times around Earth's equator!
If you counted 1 atom per second:
years to count 1 mole!
1 mole of water molecules vs. drops in all Earth's oceans:
times more than all ocean drops!
Each penny is 1.55 mm thick. The moon is 384,400 km away.
With 1 mole of pennies, you could make this trip:
