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(g) + 4 NO(g) + O₂(g) → 4N2(g) + 2CO2(g) + 4H₂O(g) Suppose that the exhaust stream of an automobile has a flow rate of 2.52 L/s at 656 K and contains a partial pressure of NO of 13.1 torr. What total mass of urea is necessary to react completely with the NO formed during 7.7 hours of driving? Express your answer using two significant figures. 15. ΑΣΦ m = ? g
