3. Propane gas (C3H8) burns completely in the presence of oxygen gas (O2) to yield carbon dioxide gas (CO2) and water vapor (H2O). Assuming that all volume measurements occur at the STP, how many liters of carbon dioxide gas will be produced in the reaction? Assuming that all volume measurements occur at the STP, how many liters of water vapor will be produced in the reaction?

Welcome to OpenStudy. First, please write out the balanced chemical equation. Next, if you are not given values for any of the substances, I would assume you use the coefficients as number of mole and use http://erhs.rcsnc.org/UserFiles/Servers/Server_4766394/Image/Donna%20Scofield/mole%20conversion%20map.bmp

But how can I tell how many liters come out of the reaction when I don't know how many go in

the book should have had specified an amount of propane (either mass of volume). If it didn't i would just take 1 L of propane gas and say that 1 L of propane gas makes x L of $CO_2$ and y L of $H_2O$
