Given the balanced equation: 16 HCl + 2 KMnO4 --> KCl + 2MnCl2 + 5Cl2 + 8 H20 If 4 moles of KMnO4 reacts, how many moles of H20 are produced?

Answer 1

 16 HCl + 2 KMnO4 --> KCl + 2MnCl2 + 5Cl2 + 8 H20

Use the coefficients to go from moles to moles.

2 mol KMnO4 = 8 mol H2O

(4 mol KMnO4 / 1) × (8 mol H2O / 2 mol KMnO4) = 4(8)/2=32/2=16

16 mol H2O
