    The number of moles is labeled with n

    n=2.8 moles

    1 mole = 6.02 * 10²³atoms

    This means that atom numbers can be calculated:

    2.8 moles * 6.02 * 1023 atoms = 16.86 * 10²³ atoms

    The mole is defined as the measurement unit for amount of substance. 1 mole contains exactly 6.02*10²³particles: atoms, molecules, ions or electrons.
