Calculation:
- The electrolysis of water involves the decomposition of water into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode.
- The balanced chemical equation for the electrolysis of water is: 2H2O(l) → 2H2(g) + O2(g)
- From the balanced equation, it is evident that for every 2 moles of water decomposed, 2 moles of hydrogen gas and 1 mole of oxygen gas are produced.
- Since 4 moles of electrons are transferred, this corresponds to the decomposition of 2 moles of water.
- Hence, the total volume of gases produced at STP can be calculated using the ideal gas law: PV = nRT
- At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 liters.
- Therefore, for 2 moles of hydrogen gas and 1 mole of oxygen gas produced, the total volume of gases at STP will be:
2 moles of H2 = 2 * 22.4 L = 44.8 L
1 mole of O2 = 1 * 22.4 L = 22.4 L
- Total volume of gases produced = 44.8 L (H2) + 22.4 L (O2) = 67.2 L
Therefore, the correct answer is option C) 67.2 L.

1 mole of O2 = 1 * 22.4 L = 22.4 L

Therefore, the correct answer is option C) 67.2 L.
