Consider the reaction below.
C3H8 + 5 O2  3 CO2 + 4 H2O
How many litres of CO2 will be produced when 10.0 L of O2 are completely
reacted with C3H8? Assume that the volumes of the reagents and products are
measured at constant pressure and temperature.

  1. With all gases in the equation one may use a shortcut in which volumes are considered as mols.
    Convert 10 L O2 to ? L CO2.
    10 L O2 x (3 mols CO2/5 mols O2) = 10 x 3/5 = ? L CO2.
