Comusion to liters

Question

Given the reaction shown here, how many liters of CO2 will be produced from the combustion of 0.750 L of C4H10 if this reaction occurs at constant temperature and pressure. 

2 C4H10 (g) + 13 O2 (g) → 8 CO2 (g) + 10 H2O (g)

Answer 1

There are multiple approaches to this problem, but the quickest is just 1 stoichiometry line!

1. Since you are told that the reaction occurs at STP (standard temperature and pressure), you can convert between liters and moles of gas using the conversion factor 1 mol = 22.4 L. Watch out in other problems - you can only use this at STP!
2. Convert away! 0.750 L C4H10 -> mol C4H10 -> mol CO2 -> L CO2

Let me know if that helps/if you need further clarification!
