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
