Reactants Elements Products
1 Al 2
1 S 3
5 H 2
7 O 13
Balanced chemical reaction
2Al(OH)₃ + 3H₂SO₄ ⇒ Al₂(SO₄)₃ + 6H₂O
Reactants Elements Products
2 Al 2
3 S 3
12 H 12
18 O 18
Sum up the coefficients
Result = 2 + 3 + 1 + 6
= 12

To determine the formula units of the given compound, we need to convert from grams to moles first then convert it to formula units by using the Avogadro's number. We do as follows:
23.5 g <span>Sb2S3 ( 1 mol / 339.7 g ) ( 6.022 x 10^23 formula units / mol ) = 4.17x10^22 formula units </span><span>Sb2S3</span>
