Chapter 10 Notes—ALL ABOUT THE MOLE!
How do I calculate molar mass?
STEP 1:
STEP 2:
STEP 3:
STEP 4:
What is a mole?
TRY IT OUT!Find the molar masses of:
NaCl H2O
SO3 PCl3
MOLAR MASS!

EVERYTHING GOES THROUGH THE MOLE!
WHAT IS A TWO-STEP CONVERSION PROBLEM?
Calculate the number of molecules in 60.0 g NO2.
1st Conversion:
2nd Conversion:
So here’s an example!
Here’s the equation:

How many moles is 2.80 X 1024 atoms of silicon?
How many moles is 2.17 X 1023 particles of bromine?
How many moles are in 20 grams of NaCl?
Determine the volume in liters of 5 moles of hydrogen gas.
Another example:Calculate the volume, in liters, of 3.24 x 1022 molecules of Cl2 (STP).
LET’S PRACTICE!
