Answer:

We know that the molar volume of an Ideal Gas at #"STP"# (check the definition!) is #22.7*L*mol^-1#...we gets a bit over #1*L#

Explanation:

We then have to find the molar quantity of dioxygen gas. Now it is a fact that ALL the elemental gases (save the Noble gases) are diatomic....i.e. #H_2, N_2, O_2, F_2.........#

And so we work out the product......

#"moles of gas"xx"molar volume......"#

#=(1.6*g)/(32.00*g*mol^-1)xx22.7*dm^3*mol^-1~=1*L#.
