Question

One of the methods of preparation of per disulphuric acid, H2​S2​O8​ involve electrolytic oxidation of H2​SO4​ at anode (2H2​SO4​→H2​S2​O8​+2H++2e−) 
with oxygen and hydrogen as by-products. In such an electrolysis, 9.722 L of H2​ and 2.35 L of O2​ were generated at STP. What is the weight of H2​S2​O8​ formed ?​
