    They both have the same number of atoms

    Explanation:

    The number that indicates the amount of particles in a compound is the Avogadro's number (NA).

    It does not matter the mass of compound we have, If we have 1 mol we will be sure that we are talking about 6.02*10²³ particles

    6.02*10²³ represents the amount of atoms in twelve grams of 12-pure carbon and it is considered a reference to measure the amount of all kinds of substances present in a given system.
