## anonymous 4 years ago how many oxygen atoms are in 4.40g of Al2(so4)3?

I always hated chemistry...

How many grams will be in 1 mole of that solution?

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.
