    Answer:a)No of moles of Aluminium=0.4703

    b)number of aluminum atoms=2.832 x 10^23 atoms

    Explanation:

    a)Given that The Amount/ Mass of Aluminum is 12.69g

    We know that

    No of moles =Mass/ Molar mass

    Molar mass of Aluminium, Al is 26.982 g/mol

    No of moles =12.69g/26.982 g/mol

    No of moles =0.4703

    Also

    b) 1  mole of aluminium must contain  6.022  x 10^23  atoms of aluminium  

    which is  known as Avogadro’s constant.

    Therefore, 0.4703 moles will contain 0.4703 x  6.022  x 10^23  atoms =2.832 x 10^23 atoms
