Mole Worksheet: moles ↔ particles
The mole is a number equal to 602,000,000,000,000,000,000,000 or 6.02 x 1023
Solve the following problem to give you an idea of how large a number this is:
How many dollars would each of the 7 billion (7,000,000,000) people of the world get if
you distributed 1 mole of pennies to each of them?
