Butane, C4H10, is a component of natural gas that is used as fuel for cigarette lighters. The balanced equation of the complete combustion of butane is
2 C4H10(g) + 13 O2(g) → 8 CO2(g) + 10 H2O(l)
At 1.00 atm and 23 °C, what is the volume of carbon dioxide formed by the combustion of 2.00 g of butane?
Express your answer with the appropriate units.
The ideal gas law PV = nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant R equals 0.08206 L ⋅ atm/(K ⋅ mol) or 8.3145 J/(K ⋅ mol). The equation can be rearranged as follows to solve for n:
This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.
