Problem: 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 8.54 mol carbon dioxide is the limiting reactant?

FREE Expert Solution

The given chemical reaction is:

2 NH3(g) + CO2(g) → CH4N2O(aq) + H2O(l)


Notice that we are given the mass of both reactants: this means we need to determine the limiting reactant, which is the reactant that forms the less amount of product


This is because once the limiting reactant is all used up, the reaction can no longer proceed and make more products.


We need to perform a mole-to-mole comparison between each reactant and CH4N2O. In order to do that, we need to determine the molar mass of CH4N2O
