How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?

1 mol of oxygen has fewer molecules.

1 mol of oxygen has more molecules.

Each sample has the same number of molecules.

The molecules cannot be compared without knowing the mass.

    Each sample has the same number of molecules.

    Explanation:

    The difference between them is their mass. It's like a pound of feathers equals a pound of iron they're both a pound.

    The correct option is "Each sample has the same number of molecules."

    Explanation:

    Avogadro's Number or Avogadro's Constant is the number of particles that form a substance (which can be atoms or molecules) and that can be found in the amount of one mole of said substance.

    The Avogadro Number value is 6,023 * 10²³ particles per mole and is characterized by being applied to any substance.

    This then indicates that the number of molecules in 1 mole of oxygen coincides with the number of molecules in 1 mole of nitrogen. The number of molecules for both cases will be 6,023 * 10²³.
