Avogadro's Law states:

Equal volumes of gases, at the same temperature and pressure, contain the same number of particles, or molecules.

So, according to Avogadro's law, one mole means 6.022 x 1023 particles (atoms or molecules, dependent upon the gas). 

Hydrogen gas is diatomic (H2). Helium gas is monatomic (He). Hence, hydrogen will have twice the number of atoms.
