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
