Final answer:
The conversion of moles of AlBr₃ to moles of aluminum sulfate requires the balanced chemical equation for the reaction, which was not provided in the question.
Step-by-step explanation:
The question asks about stoichiometry, specifically the conversion of moles of one compound to moles of another through a chemical reaction. In order to answer how many moles of aluminum sulfate can form from 4.65 mol of AlBr₃, we would need the chemical equation for the reaction involving AlBr₃ and the other reactants that produce aluminum sulfate. Without this information, we cannot determine the mole-to-mole ratio required for the conversion. However, if we had the balanced chemical equation, we could use the coefficients of the reactants and products to find out how many moles of aluminum sulfate would form from a given amount of AlBr₃.
