What is the limiting reagent in this problem? A total of 40.0 mL of 0.55 M copper (II) sulfate solution is added to a beaker containing 2.02g of zinc.

  • chemistry - ,

    CuSO4 + Zn ==> Cu + ZnSO4
    mols CuSO4 = M x L = ?
    mols Zn = grams/molar mass

    Convert mols CuSO4 to mols Cu product.
    Convert mols Zn to mols Cu product.
    The answers are not the same which means one of them is wrong. The correct answer in limiting reagent problems is ALWAYS the smaller one in the reagent producing that number is the limiting reagent.
