According to Avogadro's law, the two gases will have equal number of molecules.
From the question, we are to determine how the two gases would compare according to Avogadro's law
First, we will state the Avogadro's law
Avogadro's law states that "equal volume of all gases at the same temperature and pressure contain the same number of molecules"
Now, from the given information
We have 2 liters of hydrogen gas and 2 liters of oxygen gas at the same temperature and pressure
According to Avogadro's law, gases that are equal in volume and are at the same temperature and pressure will have equal number of molecules.
Hence, according to Avogadro's law, the two gases will have equal number of molecules.
