Strategy:
 Identify the oxidation half-reaction for water to oxygen and determine the number of electrons transferred per mole of reactant.

Step 1: Write the half-reaction

This shows that 2 moles of water produce 4 moles of electrons.

Step 2: Calculate for 1 mole of water
- For 1 mole , 2 moles of electrons are required ().
- .

Step 3: Rounding
Nearest integer .
