(C) The chemical reaction at the anode is: $2H_2O(l) ightarrow O_2(g) + 4H^+(aq) + 4e^-$Total charge passed $Q = I 	imes t = 3 \ A 	imes (10 	imes 60 \ s) = 1800 \ C$.According to the stoichiometry,$4 \ mol$ of electrons produce $1 \ mol$ of $O_2$ gas.$4 	imes 96500 \ C$ of charge produces $22.4 \ L$ of $O_2$ at $STP$.Therefore,$1800 \ C$ of charge produces volume $V = \frac{22.4 	imes 1800}{4 	imes 96500} \approx 0.1045 \ L$.The closest value is $0.1 \ L$.

Electrolysis of aqueous $Na_2SO_4$ was carried out by passing a current of $3 \ A$ for $10 \ min$. The volume of the gas $(L)$ at $STP$ at the anode of the cell is approximately
