Default difficult chemistry problem 10 pts to first correct answer!?



The emission of NO2 by fossil fuel combustion can be prevented by injecting gaseous urea into the combustion mixture. The urea reduces NO (which oxidizes in air to form NO2) according to the following reaction:
2CO(NH2)2+4NO+O2-> 4N2+2CO2+4H2O
Suppose that the exhaust stream of an automobile has a flow rate of 2.48 L/s at 635 K and contains a partial pressure of NO of 11.5 torr.

What total mass of urea is necessary to react completely with the NO formed during 8.9 hours of driving?
dont try to be funny by saying its too hard bc your NOT!
