Urea (CH4N2O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH3) with carbon dioxide as follows:
2NH3(aq) + CO2(aq) + CO2(aq) → CH4N2O(aq) + H2O(l)
In an industrial synthesis of urea, a chemist combines 129.6 kg of ammonia with 211.4 kg of carbon dioxide and obtains 161.5 kg of urea.
Determine the theoretical yield of urea. Express your answer using four significant figures.
