8g of `O_(2)`, 14 g of `N_(2)` and 22 g of `CO_(2)` are mixed in a container of 10L capacity at `27^(@)C`. The pressure exerted by the mixture in terms of atmospheric pressure is `(R=0.082" L atm K"^(-1)"mol"^(-1))`

Options

A. 1.4 atm
B. 2.5 atm
C. 3.07 atm
D. 8.7 atm

Answer

C

Explanation

As, `P=(n_(1)RT +n_(2)RT+n_(3)RT)/(V)=(n_(1)+n_(2)+n_(3)) (RT)/(V)`
`=((8)/(32)+(14)/(28) +(22)/(44)) xx (0.082xx300)/(10)=3.075` atm
