1. Ideal Gas Law

2. Static Gas Conditions
Ideal gas law shows the relationship between pressure, volume, temperature, and number of moles in a gas
If you know any three variables, you can find the fourth

3. PV = nRT P – pressure (in atm) V – volume (in L) n – number of moles
T – temperature (in K)
R – Ideal Gas Constant
= L atm/ mol K

4. Gas Law Song

5. Example 1
What pressure, in atm, is exerted by .500mole of N2 in a 10.0 L container at 25°C?

6. Example 2
What is the volume of .250 mole of oxygen at 20°C and 740 mmHg?

7. Example 3
What mass of chlorine gas is contained in a 10.0L tank at 27°C and 3.50 atm?

8. Example 4
What volume will 4.0g of hydrogen gas occupy at 25°C and 750 mmHg?
