Question

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 4.16 mol ammonia is the limiting reactant?
2 NH3(g) + CO2(g) → (NH2)2CO(aq) + H2O(l)
mols NH3 = grams NH3/molar mass NH3 = ?

mols urea = mols NH3 x (1 mol urea/2 mols NH3) = mols NH3 x 1/2 = ?

Then grams urea = mols urea x molar mass urea = ?
