Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide: Ammonia gas at 223 °C and 90. atm flows into a reactor at a rate of 497. L/min. Carbon dioxide at 223 °C and 45 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100 % yield? (Type your answer using the format 8.050e-3 for 8.050 × 10-3.) please explain steps and count sif figs, i have no idea what i am doing
