Answer
KOH is the limiting reagent
Work Step by Step
100 grams MnO2 / 86.9 grams MnO2 = 1.15 moles MnO2
1.15 moles MnO2 x 1 mole H20 = 1.15 moles H20
100 grams KOH / 56.1 grams KOH = 1.78 moles KOH
1.78 moles KOH / 2 moles H20 = 0.89 moles H20
100 grams O2 / 32 grams O2 = 3.125 moles O2
3.125 moles O2 x 2 moles H20 = 6.25 moles H20
100 grams Cl2 / 70.0 grams Cl2 = 1.43 moles Cl2
1.43 moles Cl2 x 2 moles H20 = 2.86 moles H20
KOH is the limiting reagent
