2. Ideal Gas Law
Describes physical behavior of an ideal gas in terms of P, V, T, and n
PV = nRT
R = ideal gas constant
= (L∙kPa)/(K∙mol)
= (L∙atm)/(K∙mol)
= (L∙Torr)/(K∙mol)

3. Particles take up no space No intermolecular forces
Real Gas vs. Ideal Gas
Ideal Gas
Particles take up no space
No intermolecular forces
Follows gas laws under all conditions of T and P

4. In real world NO gas is truly ideal
Most will behave like ideal gases at many T and P levels, so we can use the ideal gas law
Exception: High pressure, low temperature

5. How many moles of a gas at 100. 0°C does it take to fill a 1
How many moles of a gas at 100.0°C does it take to fill a 1.00 L flask to a pressure of 1.50 atm?

6. A deep underground cavern contains 2
A deep underground cavern contains x 106 L of methane gas at a pressure of 1.5 x 103 kPa and a T of 315 K. How many kilograms of CH4 does the cavern contain.
