Question

Four moles of electrons were transferred from anode to cathode in an experiment on electrolysis of water. The total volume of the tow gases (dry and at `STP)` produced will be approximately (in litres)
A. 22.4
B. 44.8
C. 67.2
D. 89.2

Answer 1

Correct Answer - C
From 4 moles of electron
wt. of `H_(2)` formed `=4g =44.8`litre at STP
wt. of `O_(2)` formed `=4xx8=32g`
=22.4 litre at STP
Total volume =`44.8+22.4=67.2` litres.
