Question: When an aqueous solution containing gold(III) salt is electrolyzed, metallic gold is deposited at the cathode and oxygen gas is generated at the anode. (a)

When an aqueous solution containing gold(III) salt is electrolyzed, metallic gold is deposited at the cathode and oxygen gas is generated at the anode.
(a) If 9.26 g of Au is deposited at the cathode, calculate the volume (in liters) of O2 generated at 23°C and 747 mmHg.
(b) What is the current used if the electrolytic process took 2.00 h?
