1
The Ideal Gas Law PV = nRT

2
**Ideal Gas Law P = pressure – in atm, Pa, or torr**

V = volume – we will always use liters N = number of moles R = ideal gas constant T = temperature – always in Kelvin

3
**Ideal Gas Law R values If pressure is in atm, R = .0821 L atm/K mol**

If pressure is in Pa, R = x 103 L Pa/K mol If pressure is in torr (mm of Hg), R = L Torr/K mol

4
Ideal Gas Law If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature?

5
**Ideal Gas Law Begin by listing what you know and want: P = V = n = R =**

6
**Ideal Gas Law Begin by listing what you know and want: P = 5.6 atm V =**

R = T =

7
**Ideal Gas Law Begin by listing what you know and want: P = 5.6 atm**

V = 12 liters n = R = T =

8
**Ideal Gas Law Begin by listing what you know and want: P = 5.6 atm**

V = 12 liters n = 4 moles R = T =

9
**Ideal Gas Law Begin by listing what you know and want: P = 5.6 atm**

V = 12 liters n = 4 moles R = L atm/K mol T =

10
**Ideal Gas Law Begin by listing what you know and want: P = 5.6 atm**

V = 12 liters n = 4 moles R = L atm/K mol T = x

11
**Ideal Gas Law 5.6(12) = 4(.0821)x 67.2 = .3284x X = 204 K**

Substitute in information and solve for x 5.6(12) = 4(.0821)x 67.2 = .3284x X = 204 K
