Words can be a
handy way to talk
about numbers,
especially if…
Atoms are really small
So, whenever there are enough of them
that you can see it, that’s a LOT of atoms!
Nobody would want to count them
Chemists talk about groups of atoms
called moles
Did you say
MOLE?
I’m pretty
sure she
did…
A mole in Chemistry is just an amount (like
dozen)- so chemists can talk about groups
of atoms
It’s
6.02 x 1023
Why 6.02 x 1023, you ask?
That’s the # amu it takes to make 1g
Sometimes it’s called Avogadro’s number,
named after this handsome chap
6.02 x 1023 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!
6.02 x 1023 is awfully big…
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
earth’s oceans
6.02 x 1023 is awfully big…
If you lined up that many animal moles,
they would stretch
From earth to alpha centauri
2 million times!
6.02 x 1023 is awfully big…
Avogadro’s 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 1023 is awfully big…
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 6.02x1023, it would take
2,845,590 years!
Mole Pictures!
Draw a picture which includes
Mole
Avogadro
6.02 x 1023
Get creative and colorful!
