How much is a… 1.Pair 2.Trilogy 3.Gross 4.Score 5.Dozen 6.Octet 7.Quartet 8.Bakers Dozen 9.Grand 2 3 144 20 12 8 4 13 1000 Words can be a handy way to talk about numbers, especially if…

4
Atoms are really small So, whenever there are enough of them that you can see it, thats a LOT of atoms! Nobody would want to count them Chemists talk about groups of atoms called moles

5
Did you say MOLE? Im pretty sure she did…

6
A mole in Chemistry is just an amount (like dozen)- so chemists can talk about groups of atoms Its 6.02 x 10 23

7
Why 6.02 x 10 23, you ask? Thats the # amu it takes to make 1g Sometimes its called Avogadros number, named after this handsome chap

9
6.02 x 10 23 is awfully big… If I gave all of the citizens of the US (about 300 million) 1 mole of dollar bills and everyone spent 100 dollars a second It would still take 636,000 years for it to be spent! If you had a mole of pennies and gave away $1 million a day, it would take you more than 3000 years to give away all of your money!

10
The mass of that many animal moles would weigh More than 1.3 times the mass of the moon More than 60 times the combined mass of the earths oceans 6.02 x 10 23 is awfully big…

11
If you lined up that many animal moles, they would stretch From earth to alpha centauri 2 million times! 6.02 x 10 23 is awfully big…

12
Avogadros number of popcorn kernels would cover the earth with a depth of over 9 miles Pop cans would cover it 200 miles deep A mole of basketballs would make a new planet the size of earth 6.02 x 10 23 is awfully big…

13
If you count 1 number a second, it would take you 11.5 days to count to 1 million If everyone on the planet collectively counted to 6.02x10 23, it would take 2,845,590 years! 6.02 x 10 23 is awfully big…

14
Your turn! How much would a mole of rice grains weigh? How about marshmallows… how deep would a mole of marshmallows cover the earth?

15
Mole Pictures! Draw a picture which includes Mole Avogadro 6.02 x 10 23 Get creative and colorful!
