Are my answers to these Chemistry problems correct? (My answer is in bold.)

Question

For the following questions, use the following: A gas grill burns Propane (C₃H₈) in the presence of more than sufficient Oxygen (O₂). This reaction produces water vapor and Carbon Dioxide. The temperature and pressure conditions are such that 1 mole of each gas occupies 1 liter of volume.

* What is the balanced equation for this reaction?

A. C3H8 + 4O2 → 2CO2 + 4H2O

B. C3H8 + 5O2 → 3CO2 + 4H2O

C. 2C3H8 + 6O2 → 6CO2 + 8H2O

D. 2C3H8 + 5O2 → 6CO2 + 4H2O

E. None of the Above

 

* If 15 liters of Propane are completely consumed, how many liters of water vapor will be produced?

A. 7.5 L H2O (g)

B. 15 L H2O (g)

C. 30 L H2O (g)

D. 45 L H2O (g)

E. 60 L H2O (g)

 * If 15.00 liters of Propane are completely consumed, how many grams of Propane were there?

A. 40.08 g Propane

B. 80.16 g Propane

C. 160.32 g Propane

D. 320.64 g Propane

E. None of the Above

* If 15.00 liters of Propane are completely consumed, how many grams of Carbon Dioxide are produced?

A. 15 L CO2

B. 45 L CO2

C. 660. g CO2

D. 1980. g CO2

E. 1.98 × 105 g CO2

Answer 1

I agree with all of your answers.

For the third question, I got 660 g of propane, which is not one of the choices.
