The balanced chemical reaction is written as:

2H2+O2 = 2H2O

We are given the amount of H2 gas to be used in the reaction. This will be used as the starting point for the calculations. We calculate as follows:

.050 L H2 ( 1 mol H2 / 22.4 L H2 ) ( 1 mol O2 / 2 mol H2 ) ( 22.4 L / 1 mol ) = 0.025 L O2 or 25 mL O2
