x atm = x mmHg = x Pa
1 atm = 760 mmHg = 101,325 Pa

Robert Boyle's Law
Robert Boyle showed that for gas at a constant temperature, pressure and volume are inversely proportional.
P_{1}V_{1} = P_{2}V_{2}

Avogadro's Law
Amadeo Avogadro postulated that V, the volume of a gas and n, the number of gas particles are directly proportional, when the temperature and pressure are held constant.
 V_{1} V_{2}
  = 
 n_{1} n_{2}

GayLussac's Law
Their data showed that for a container of gas held at constant pressure, the volume and temperature are directly proportional.
 P_{1} P_{2}
  = 
 T_{1} T_{2}

K = constant
What is the number for atm?
What is the number for Kpa
 atm K = 0.08206
 KPa = 8.3145

What is the Ideal gas Law?
PV = nRT

Formula for Density is?
 D = Molar Mass (g/mol)
 
 Molar Volume (L/mol)
*You can get the mass from n (moles)
m = molar mass

How much does 1 mole of ideal gas occupy at STP?
22.4L

The total pressure of all gasses in a sealed container is equal to what?
Dalton's Law.
The Pressure of each gas added together.
P_{total}=P_{1}+P_{2}+P_{3}+.....

A partial pressure is the pressure exerted by just one type of gas in a mixture. What is the formula of partial pressure?
 P_{1}=n_{1}RT
  P Total
 V
 P_{2}=n_{2}RT
  P Total
 V
etc.......

What us the formula for mole fraction?
The mole fraction, X, represents the concentration of the component in the gas mixture, so
 X_{1}= moles of component 1
 
 total moles in mixture

1 gallon is how many liters?
3.785L

Fahrenheit to Celsius
(9/5)C + 32 = F

Graham's Law of effusion
Put the heavier gas on bottom.
