### More Mole Conversions

During class, we learned that there are more mole conversions.  You can convert from grams to particles!! Or moles to # of atoms in particles!! Seems like a lot...
The units in these conversions are:
-Grams
-Moles
-Particles/Atoms/Molecules/Formula Units
-# of Atoms in Particles

From Grams to Moles, you multiply using 1 Mole
MMg

From Moles to Grams, you multiply using   MMg
1 Mole
MMg = Molar Mass grams

From Moles to Particles/Atoms/Molecules/Formula Units, you multiply using
6.022 x 10^23 Particles
1 Mole

From Particles/Atoms/Molecules/Formula Units to Moles, you multiply using
1 Mole
6.022 x 10^23 Particles

From Particles/Atoms/Molecules/Formula Units to # of Atoms in Particles, you multiply using
# of Atoms
1 molecule

From # of Atoms in Particles to Particles/Atoms/Molecules/Formula Units, you multiply using
1 molecule
# of Atoms

Conversions from Particles to Mass
Ex. What is the mass of 2.78 x 10^22 Fe Atoms?
2.78 x 10^22 Fe Atoms x                 1 Mole                x      55.8 g (Molar Mass)
6.022 x 10^23 Fe Atoms                 1 Mole
= 2.58 g

Ex. What is the mass of 8.4 x 10^18 SO3 molecules?
8.4 x 10^18 molecules x                 1 Mole                 x 8.01 g (Molar Mass)
6.022 x 10^23 Molecules               1 Mole
= 1.1 x 10^-3 g OR 0.0011 g

Conversions from Grams to Particles
Ex. How many atoms of Iron in 20.0 g of Iron?
20.0 g x           1 Mole               x  6.022 x 10^23 Atoms
55.8 g (Molar Mass)               1 Mole
= 2.16 x 10^23 Atoms of Fe

Here is a video that demonstrates from Grams to Atoms (Skip to 4:10 in the video)

Ex. How many formula units of KMnO4 in 0.240 g of KMnO4?
0.240 g x 1 Mole    x  6.022 x 10 ^23
158.0 g             1 Mole
= 9.15 x 10^20 Formula Units

QUIZ NEXT CLASS (Nov.25) ON MOLE CONVERSIONS!!!!!
QUIZ HOOOOOOOOOOOOOOOOOOO! RIGHT ON! OKAYY!!!
