Four moles of electrons were transfered from anode to cathode in an ex...
If number of moles of electron transferred=4
Number of moles of oxygen liberated=1
Number of moles of hydrogen liberated=2
So total moles of gases =3
Volume of gases =3x22.4=67.2litre
C is the correct answer.

Answer:
Explanation:
In the process of electrolysis of water, the water molecule (H2O) is broken down into its constituent elements, hydrogen (H2) and oxygen (O2), through the transfer of electrons.
Given that four moles of electrons were transferred, we can use Faraday's law to determine the amount of gas produced. According to Faraday's law, one mole of electrons is equivalent to one Faraday of electricity, which is approximately 96,500 coulombs.
Step 1: Convert moles of electrons to coulombs:
4 moles of electrons x 96,500 coulombs/mole = 386,000 coulombs
Step 2: Calculate the moles of hydrogen and oxygen produced:
For every mole of electrons transferred, one mole of hydrogen gas is produced at the cathode, and half a mole of oxygen gas is produced at the anode.
Moles of hydrogen gas = 4 moles
Moles of oxygen gas = 4/2 = 2 moles
Step 3: Convert moles of gases to volume at STP:
At Standard Temperature and Pressure (STP), one mole of any gas occupies a volume of 22.4 liters.
Volume of hydrogen gas = 4 moles x 22.4 L/mole = 89.6 liters
Volume of oxygen gas = 2 moles x 22.4 L/mole = 44.8 liters
Step 4: Calculate the total volume of the two gases:
Total volume = Volume of hydrogen gas + Volume of oxygen gas
Total volume = 89.6 liters + 44.8 liters = 134.4 liters
Answer:
The total volume of the two gases produced in the electrolysis of water experiment is approximately 134.4 liters.
