Urea, which has the chemical formula (NH2) 2CO, is a fertilizer that can be prepared by reacting ammonia (NH3) with carbon dioxide (CO2). Given the following chemical equation, what is the theoretical yield of urea (in grams) if 4.02 mol ammonia is the limiting reactant? 2 NH3 (g) + CO2 (g) → (NH2) 2CO (aq) + H2O (l).

So 2 mole NH3 gives 1 mol urea

then 4.02 moles gives 2.01 moles of urea!

so in gram = no of moles * molecular formula mass

= 2.01*60.06

= 120.72 grams ... your answer!
