Answer 1

ANSWER

Equal volumes of gases, at the same temperature and pressure, contain the same no. of particles or molecules. So, according to avogadro's law, one mole means 6.022×10^23 particles( atoms or molecules, dependent upon the gas).

Since, Hydrogen gas is diatomic and Helium gas is monoatomic. Therefore, Hydrogen will have twice the no. of atoms.
