How many moles of aluminum sulfate can be formed from the reaction 2.5 moles of copper (II) sulfate? 2Al+3CuSO_(4)arrow Al_(2)(SO_(4))_(3)+3Cu

## Step1: In the balanced chemical equation, we see that 3 moles of copper (II) sulfate ( ) react to form 1 mole of aluminum sulfate (\(Al_{2}(SO_{4})_{3}\)). This is a 3:1 ratio.### \(3 CuSO_{4} \rightarrow Al_{2}(SO_{4})_{3}\)## Step2: To find out how many moles of aluminum sulfate can be formed from 2.5 moles of copper (II) sulfate, we can set up a proportion based on the stoichiometry of the reaction.### \(\frac{3 moles\: of\: CuSO_{4}}{1 mole\: of\: Al_{2}(SO_{4})_{3}} = \frac{2.5 moles\: of\: CuSO_{4}}{x moles\: of\: Al_{2}(SO_{4})_{3}}\)## Step3: Solving for x, we get:### \(x = \frac{2.5 moles\: of\: CuSO_{4}}{3} = 0.833 moles\: of\: Al_{2}(SO_{4})_{3}\)Hence, 0.833 moles of aluminum sulfate can be formed from the reaction of 2.5 moles of copper (II) sulfate.
