Be sure to answer all parts. 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 6.05 g of Au is deposited at the cathode, calculate the volume of 02 generated at 23°C and 752 mmHg. (b) What is the current used if the electrolytic process took 4.30 h?
