Determine the theoretical yield of H₂S (in moles) if 4.0 mol Al₂S₃ and 4.0 mol H₂O are reacted according to the following balanced reaction.A possibly useful molar mass is Al₂S₃= 150.17 g/mol.
Al₂S₃(s) + 6 H₂O(l) → 2 Al(OH) ₃(s) + 3 H₂S(g)

Question

Quizplus · Accepted Answer

The limiting reactant is H₂O, as 6 moles of H₂O are needed per mole of Al₂S₃. With 4 moles of H₂O, only 2/3 of a mole of Al₂S₃ can react, producing 2 moles of H₂S.
