In the electrolysis of an acid solution, oxygen can be produced by the following half-reaction:
2H2O(l) → O2(g) + 4H+(aq) + 4e^-
How many moles of O2 can be produced from a solution that was electrolyzed for 7.00 h using a current of 6.40 A?
1.16 × 10^-4 mol
3.89 × 10^9 mol
2.59 × 10^8 mol
0.418 mol
1.67 mol
