The reaction A B+C has been carried out and the following graph reported:

where m= 8.

To achieve 71 % total conversion of A, two CSTR are placed in series and they are designed in a way that the fist reactor shows 32% conversion and the second reactor increases the conversion to the desired amount ( 71 %). what is the total volume of both reactors together in litre if the entering molar flow rate of A was 9.3 mol/hr ?

Report your answer up to 2 decimal point. Do not truncate any intermediate step, but only the final answer.
