 M3.5   STOICHIOMETRY BRIDGE FOR REACTING GAS VOLUMES 

The mathematical operations required to solve   gas-volume – gas-volume  stoichiometry problems successfully are conveniently depicted using a STOICHIOMETRY BRIDGE.

DEPICTS REACTANT GAS-VOLUME INPUT & PRODUCT GAS-VOLUME OUTPUT

N.B. This picture may need adjusting slightly where the volume of one gaseous reactant needed to be equated with another, e.g., with the combustion of a gas in oxygen.  Here, a pair of inputs, one whose value is known, is related to the other by the reaction stoichiometry.
