Air contains 21% oxygen, 70% nitrogen, 5% carbon dioxide and 4% moisture by volume. The atmospheric pressure is 760 torr. What is the partial pressure of each gas in torr?

Solution

Partial pressure
$equals space fraction numerator Volume space of space gas over denominator Total space volume end fraction space cross times space Total space pressure therefore space space space space Partial space pressure space of space straight O subscript 2 space equals space 21 over 100 cross times 760 space equals space 159.6 space torr space space space Partial space pressure space of space straight N subscript 2 space equals space 70 over 100 cross times 760 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 532.0 space torr$
$Partial space pressure space of space CO subscript 2 space equals space 5 over 100 cross times 760 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 38.0 space torr$
Partial pressure of moisture = $4 over 100 cross times space 760 space equals space 30.4 space torr$
