is helium lighter than hydrogen?

Hydrogen (atomic weight 1, but exists as pairs of atoms (diatomic), molecular weight 2), should weigh 2g per 24 litres at room temperature, whereas Helium (exists as lone atoms (monatomic), atomic weight 4), should weigh 4g per 24 litres at room temperature.
So the answer is No.
Hydrogen is lighter than helium.
We hope that clarifies your query.
