when methane is burned in oxygen, it yields carbon dioxide and water. If I need 25 L of carbon dioxide, how much methane should I begin with? Also, how much oxygen should I use to yield 25 L of carbon dioxide?

Thanks,

Start with reaction equation.

CH4   +  2O2   --------->    CO2   +  2H2O

Here 1 mole of methane , i.e  16g of CH4 produces 22.4l of CO2 assuming the reaction takes place at NTP.Therefore, 17.85g of it produces 25l. You can find similary the amount of Oxygen required for the same. (it comes to be 2.232 moles)

Is this the right equation to start out with?: CH4 + 2O2 ----> CO2 + 2H2O
