what is the valence configuration of aluminium?
Pretty easy to doCalculate how much that whole molecule weighsThen calculate how much each of them separately weighs and divide the Individual by the Total, then multiply x 100 to get your percentageRemember that S and O are inside the parenthesis for 2, so you'll have 2 Sulfurs and 8 Oxygens in the molecule (multiply the mass by that then divide by the total)I'd do this but it's really late and I don't have a periodic table close by, but that should get you throughHope this helps.
Aluminum has 3 electrons in its outermost shell and gives up those electrons to form an ion with a positive 3 charge.
