6.9 mol H2O. The reaction of 3.45 mol of KMnO4 produces 6.9 mol of water.
(a) Write the partially balanced equation in terms of O.
We assume that all the water comes from the O in KMnO₄.
KMnO₄ + … → 4H₂O + …
(b) Use the molar ratio of H₂O:KMnO₄ to calculate the moles of water.
Moles of water = 3.45 mol KMnO₄ x (4 mol H₂O/1 mol KMnO4) = 13.8 mol H₂O
