Explanation:
According to Avogadro's law, equal volume of all gases under similar conditions of temperature and pressure contain equal number of molecules.
As such
No. of molecules of H2 = No. of molecules of O2
w×N02=4.8×N032
where N0 = Avogadro's number (6.02×1023) and ω = mass of H2 (in g)
∴ω=4.8×232 = 0.3 g
