Solution

The correct option is B 0.28 atm
Let 1 mol of gas is present.So, 22.4 L will be volume of the mixture
$D e n s i t y = \frac{m a s s}{v o l u m e}$
Molar Mass of Mixture is $1.3 \times 22.4 = 29.12$ $g / m o l$
% of oxygen present in mixture = x
% of nitrogen present in mixture = 1-x
Molar Mass of oxygen and nitrogen are 32 and 28 g/mol respectively
32(x) + 28(1-x) = 29.12
x = 0.28
Partial pressure of $O_{2}$ is 0.28 atm
