Propane (C3H8) burns in oxygen to produce carbon dioxide and water vapor. The balance equation for this reaction is C3H8 + 5O2 ----> 4H20 + 3CO2. What volume of carbon dioxide id produced when 2.8 L of oxygen are consumed?

Here are the steps for solving stoichiometry problems.
Step 1. Write the balanced chemical equation. You have done that.

Step 2. Convert what you have into mols. Remember 1 mol of a gas @ STP occupies 22.4 L; therefore,
2.8/22.4 =?? mols O2.

Step 3. Use the coefficients in the balanced equation to convert mols of what you have (in this case mols oxygen) to mols of what you want (in this case mols CO2).

Step 4. Convert mols from step 3 to liters by reversing the equation used in step 2.

Post your work if you get stuck.
