Explain: “The number of atoms in 1 mole of hydrogen is twice the number of atoms in 1 mole of helium at the same pressure and temperature.”

Answer:

The reason for this is that hydrogen gas is diatomic, but helium gas is monoatomic, and as a result, they are diatomic. When comparing the number of atoms in one mole of hydrogen to the number of atoms in one mole of helium, hydrogen has twice the number of atoms.
