Benzaldehyde is produced from toluene by the following catalytic reaction (see figure):
Dry air and toluene vapor are fed to the reactor at 350 F and 1 atm. Air is supplied 100% in excess. Of the toluene that is fed to the reactor, 13% reacts to form benzaldehyde and 0.5% reacts with oxygen to form CO2 and H2O. The gases produced leave the reactor at 379 F and 1 atm. Water is circulated through the jacket surrounding the reactor, and it enters at 20 ° C and exits at 55 ° C.

a. Moles of benzaldehyde formed (mol)?Note: Do not use decimals for your answer.
b. Moles of toluene that did not react (mol)?
