You have two SCUBA tanks, one containing air( 80% 20%) and the other containing a nitrox mix that is 60% nigtrogen and 40% oxygen. The volume of each tank is 10.00 L. Determine the number of moles of nitrogen and oxygen in the air tank.
Wouldn't that be 80% of 10 for N2 and 20% of 10 for volume. Then L/22.4 = mols.
