    Solve this first: \[4.40 g Al _{2}(SO _{4})_{3} \times (\frac{ 1 mole Al _{2}(SO _{4})_{3} }{ ? g Al _{2}(SO _{4})_{3} })\]

    Then find how many moles of O is in Al2(SO4)3. How much does that amount of moles weigh in grams? Then lastly multiply that number with Avogardo's number to determine how many atoms.
