Chem HW!! Difficult! HELP!

posted by .

Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide.

2 NH3(g) + CO2(g) ---Heat pressure---> H2NCONH2(s) + H2O(g)

Ammonia gas at 223°C and 90. atm flows into a reactor at a rate of 610. L/min. Carbon dioxide at 223°C and 48 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?

i do not know if i got it right, please help!! i got 42000 g/min
