The combustion of propyne, CH3 − C ≡ CH, releases heat when it burns according to the following equation: (9.1, 9.2,

9.3, 9.4)

C3H4(g) + 4O2(g) 3CO2(g) + 2H2O(g)

a. How many moles of O2 are needed to react completely with 0.225 mol of C3H4?

---

b. How many grams of water are produced from the complete reaction of 64.0 g of O2?

---

c. How many grams of CO2 are produced from the complete reaction of 78.0 g of C3H4?

---

d. If the reaction in part c produces 186 g of CO2, what is the percent yield of CO2 for the reaction?
