How many liters of Chlorine at STP will react with 35L of 02 at STP given the following reaction?
2Cl2(g) + 7O2(g) - 2Cl2O7(l)
You can use regular stoichiometry to solve this problem or you can take a shortcut. The shortcut works this way. Instead of converting to moles, if all of the reactants and products are in the gaseous form, volume may be used as if volume = moles.
Therefore, use the coefficients to convert L of one reagent to L of another.
35L O2 x (2 moles Cl2/7 moles O2) = ??L Cl2.
10 L Cl2
