Burning 1 mol of propane in a gas grill adds 132.0 g of carbon dioxide (CO2) to the atmosphere. What volume of CO2 does this correspond to at STP?

Question

Burning 1 mol of propane in a gas grill adds 132.0 g of carbon dioxide ([latex]CO_{2}[/latex]) to the atmosphere. What volume of [latex]CO_{2}[/latex]does this correspond to at STP?
Analysis
To solve this problem, we must convert the number of grams of [latex]CO_{2}[/latex]to moles using the molar mass. The number of moles of [latex]CO_{2}[/latex]can then be converted to its volume using a mole–volume conversion factor (1 mol/22.4 L).

Accepted Answer

[1] Identify the known quantities and the desired quantity.

132.0 g [latex]CO_{2}[/latex] ? L[latex]CO_{2}[/latex]
known quantity desired quantity

[2] Convert the number of grams of [latex]CO_{2}[/latex]to the number of moles of [latex]CO_{2}[/latex]using the molar mass.

[3] Convert the number of moles of [latex]CO_{2}[/latex]to the volume of [latex]CO_{2}[/latex]using a mole–volume conversion factor.
