    Answer:One mole of a substance contains 6.02*10∧23 particles,

    1 mole of a aluminium contains 27 g

    35 g of aluminium contains 35/27 = 1.296 moles

    Thus, the number of particles will be 1.296 * 6.02 * 10∧23

    = 7.804 * 10∧23 particles,

    Hence, 35 g of Aluminium contains 7.804 * 10∧23 atoms
