Question

3. A mixture of gases- oxygen, carbon dioxide and nitrogen - exerts a total pressure of 107.6 kPa. If the oxygen
exerts 45.8 kPa and the carbon dioxide exerts 37.1 KPA, then what is the partial pressure of the nitrogen?

Answer 1

Answer:  23.7kPa

Explanation:  Given:

                     P total= Sum of partial P of all gases in the mix

                 P total = PO2 +PN2 +PCO2

                 107.6 = 45.8 + PN2 +37.1

                   PN2= 107.6- (45.8+ 37.1)

                           = 107.6- 83.1

                           = 23.7kPA

      Therefore  Partial pressure of Nitrogen is 23.7 kPA
