  • 1. Given the following reaction: (hint: balance the equation first)

    Na2SO4 + 2 AgNO3 g 2 NaNO3 + Ag2SO4

    If you start with 60 mL of a 3.0 M Na2SO4 solution and 40 mL of a 3.0 M AgNO3 solution,

    a) determine the limiting reagent AgNO3

    b) using the information from part a, determine the theoretical yield of Ag2SO4
    18.71 g Ag2SO4

    c) determine the number of grams of excess reagent left 17.04 g Na2SO4



    2. Given the following equation:

    Ca(OH)2 + 2 HClO4 g 2 H2O + Ca(ClO4)2

    a) If 40 mL of a 1.0 M HClO4 solution is reacted with 60 mL of a 1.5 M Ca(OH)2 solution, determine the limiting reagent HClO4

    b) Determine the number of moles of H2O produced 0.04 mol H2O

    c) Determine the number of grams of Ca(ClO4)2 produced 4.78 g Ca(ClO4)2

    d) Determine the number of grams of excess reagent left over in the reaction
    5.19 g Ca(OH)2
