3. A gas mixture contains 50 mol% H2 and 50 mol% He.
1.00-L samples of this gas mixture are mixed with
variable volumes of O2 (at 0 °C and 1 atm). A spark is
introduced to allow the mixture to undergo complete
combustion. The final volume is measured at 0 °C and 1
atm. Which graph best depicts the final volume as a
