Combined Gas Law and Dalton’s Partial Pressure Law Chapter 12

The Combined Gas Law It combines the previous three laws in the following mathematical expression: P1 x V1 P2 x V2 = T1 T2

Sample Problem The volume of a gas filled balloon is 30.0 L at 40.0 0C and 153 kPa pressure . What volume will the balloon have at standard temperature and pressure?

Dalton’s Law of Partial Pressure The pressure exerted by a gas in a mixture is unaffected by the presence of the other gases. The total pressure of gases is the sum of the partial pressures of its components.

Dalton’s Law The mathematical expression is Pt = P1 + P2 + P3 + ……

Sample Problem A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.9 kPa. If PO2 = 6.6 kPa and PN2 = 23.0 kPa, What is PCO2?
