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)→CH₄N₂O(aq)+H₂O(l) In an industrial synthesis of urea, a chemist combines 139.8kg of ammonia with 211.4kg of carbon dioxide and obtains 170.8 kg of urea. Determine the theoretical yield of urea Express your answer using four significant figures
