Ounce Penny
A look at what is currently available on eBay
How many platinum atoms could you buy with a penny?
Platinum (195.078) sold for $1500/oz. One ounce is equal to 28.35 g.
1 cent x (1$ / 100 cents) x (1 oz / $1500) x (28.35g / 1 oz) x (1 mole / 195.078g) x (6.022x10^23 atoms / mole) = 5.83x10^17 atoms.
**********
the lesson and the math is "factor label method".. aka "dimensional analysis"..
do you understand what I did?
any questions?
