A mole of pennies stackd on top of one another would reach from here to the sun and back how many times?
Need more information:
1. average thickness of penny
2. distance from earth to sun
3. you need to understand avogadros number. (6.0221415 × 10^23) Then it becomes a simple math problem.
but then what after you get that info?
2.918 billion pennies
