4.3 Exercise 12

Avg difficulty 2.5

Urea, CO(NH2)2, is manufactured on a large scale for use in producing urea-formaldehyde plastics and as a fertilizer. What is the maximum mass of urea that can be manufactured from the CO2 produced by combustion of 1.00×103kg1.00 \times 10^{3} \text{kg} of carbon followed by the reaction?
CO2(g)+2NH3(g)⟶CO(NH2)2(s)+H2O(l)\text{CO}_{2} \left(g\right) + 2 \text{NH}_{3} \left(g\right) \rightarrow \text{CO} \left(\text{NH}_{2}\right)_{2} \left(s\right) + \text{H}_{2} \text{O} \left(l\right)
