Answer the following questions using the unbalanced chemical equation. The final answers will be
answered to three significant digits. SHOW ALL WORK!
C3H8 +
O₂ →
H₂O +
CO2
1) If 28.0 grams of C3Hs react with 45.0 grams of Oz gas how many grams of water can be formed
(theoretical)? What are the limiting and excess reactants? How many grams of the excess
reactant remain when the reaction stops? If 12.6 grams of water are actually produced, what is
the percent yield of water?
Honors (required) and bonus for all others: How much more of the limiting reactant is required to
completely use up the excess in moles?
