Answer:

Well, the #"molar volume at STP"# is #22.4*L*mol^-1#. I make it approx. #400*mL#.

Explanation:

And so we work out the molar quantity of dioxygen gas......(and most of the elemental gases are binuclear) and calculate the volume..

#"Volume"=(0.50*cancelg)/(32.00*cancelg*cancel(mol^-1))xx22.4*L*cancel(mol^-1)=??*L#
