Question

16 gram of oxygen, 14 gram of nitrogen and 11 gram of carbon dioxide are mixed in an enclosure of volume 5 L and temperature `27^(@)C. The pressure exerted by the mixture is
A. `4xx10^(5)Nm^(-2)`
B. `5xx10^(5)Nm^(-2)`
C. `6xx10^(5)Nm^(-2)`
D. `9xx10^(5)Nm^(-2)`

Answer 1

Correct Answer - C
`p=p_(1)+p_(2)+p_(3)=((nRT)/(V))_(1)+((nRT)/V)_(2)+((nRT)/V)_(3)`
`" " =(n_(1)+n_(2)+n_(3))(RT)/(V)`
`" "=((0.5+0.5+0.25)(8.31)(300))/(5xx10^(-3))`
`" "6.23xx10^(5)Nm^(-2)`
