2. When doing word problems….
Find the question word: determine what you are looking for.
What #s did the problem give you
If only one # always start grid with that #
If Multiple #’s you need a formula

3. Variables that describe a Gas
P= Pressure T = Temperature n= Amount V= Volume

4. Ideal Gas Law
PV =nRT R = gas constant R = 8.31 LkPa R= Latm moleK moleK R= 62.4 mmHg L all other units can mole K be converted
