A spark was passed through a 50 cm3 sample of a H2/O2 mixture in a gas buret at 18°C and 1.00 atm; the formation of water went to completion. The resulting dry gas had a volume of 10 cm3 at 18°C, 1.00 atm. What was the initial mole fraction of H2 in the mixture if (a) the residual gas after sparking was H2, (b) the residual gas was O2?
What? It seems easy but I have no idea where to even start.....what the heck is a residual gas?
