A vessel of volume `4` litres contains a mixture of `8g` of `O_(2), 14g` of `N_(2)` and `22 g` of `CO_(2)` at `27^(0)C` . The pressure exerted by the mixture is

Options

A. `10 N//m^(2)`
B. `5 xx 10^(6) N//m^(2)`
C. `7.69 xx 10^(5) N//m^(2)`
D. `6 xx 10^(5) N//m^(2)`

Answer

C

Explanation

`PV = (m)/(M)RT, P = (RT)/(V)[(m_(1))/(M_(1))+(m_(2))/(M_(2))+(m_(3))/(M_(3))]`
