  • chemistry need help -

    find the number of moles of al.

    then multiply by avagradro's number.

  • chemistry need help -

    1. Divide the grams of aluminum by the molar mass of aluminum (26.98g/mole) to convert mass to moles.

    2. Multiply the number of moles of aluminum by Avogadro's Number (6.02x10^23 atoms/mole).
