Answer:

If there are equal masses of gases, dihydrogen will exert more pressure.........

Explanation:

If there are equal numbers of molecules, then dihydrogen and dioxygen will exert the SAME PRESSURES.............

Pressure is a state function of temperature, and of the number of gaseous molecules...........this can be appreciated by the Ideal Gas equation, #PV=nRT#. To a first approx., if there are equal numbers of molecules, and an equal temperature, these gases will exert the same pressure.
