If you had Avagadro’s number of pennies, how many dollars would you have? Do you think you would have enough money to buy yourself a house?

Avagadro's number is 6.02 x 10^23, we know that there is one dollar for every 100 pennies. So if we divide Avagadro's number by 100, we would get $6.02 x 10^21 dollars.

This translates to $6,022,000,000,000,000,000,000 dollars.

I'd say I'd be able to buy myself more than just ONE house.
