If O2(g) and H2(g) are in separate containers of equal pressure, volume and temperature, which one of these statements is true? The amount of moles in the O2 container is greater than that in the H2 container. There are more molecules in the H2 container than molecules in the O2 container. If you increase the pressure in both containers, but keep temperature constant, the volume of both containers will increase If you increase the pressure in both containers, but keep...
