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.
P1V1 = P2V2
-
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.
-
Gay-Lussac's Law
Their data showed that for a container of gas held at constant pressure, the volume and temperature are directly proportional.
-
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.
Ptotal=P1+P2+P3+.....
-
A partial pressure is the pressure exerted by just one type of gas in a mixture. What is the formula of partial pressure?
-
What us the formula for mole fraction?
The mole fraction, X, represents the concentration of the component in the gas mixture, so
- X1= 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.
