About 8.0 × 106 tons of urea [(NH2)2CO] are used annually as a fertilizer. The urea is prepared at
200°C and under high-pressure conditions from carbon dioxide and ammonia according to the
following unbalanced equation: Calculate the volume of ammonia (in liters) measured at 150
atm needed to prepare 1.0 ton of urea.
(1 ton = 103 kg)
CO2(g) + NH3(g) → (NH2)2CO(s) + H2O(g)
