A mixture of gases at `760 mm` pressure contains `65%` nitrogen `15%` oxygen and `20%` carbon dioxide by volume What is partial pressure of each in mm ? .

Options

A. 494, 114, 252
B. 494, 224,152
C. 494, 114, 152
D. None of these

Answer

C

Explanation

`P'_(N2) = 760 xx(65)/(100) =494 mm`
`P'_(O2) = 760 xx ( 15)/( 100) = 114 mm`
`P'_(CO2) =760 xx (20)/(100) =152 mm`
