3. (Problem) Urea is a common fertilizer that is prepared by the reaction of ammonia with
carbon dioxide:
2 NH3(aq) + CO2(aq) → CHAN2O(aq) + H2O(1)
a) How many grams of urea can be formed from the reaction of 1.36 x 103
grams
ammonia?
b) How many grams of water will be produced when 1.3 moles of ammonia are reacted?
4. (Problem) The goal of these questions are to help you become comfortable with setting up
and solving stoichiometry questions quickly. The focus is ply on setting them up and
determining what information you need (molar mass of... etc).
Iron (III) oxide reacts with carbon monoxide according to the equation:
Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g)
a) If 22.55 g Fe2O3 is reacted with excess CO, how many grams of iron can be made?
b) If we want to refine 10.0 kg of iron metal, how many moles of carbon monoxide gas do we
need?
c) If 2.50 moles of Fe2O3 is reacted with carbon monoxide, how many liters of carbon dioxide
gas form?
