To determine the liters of oxygen gas, we convert the 37.4 grams of water to moles, which is 2. 078 moles. The moles oxygen is half the moles of water which is equal to 1.039 moles. Using ideal gas equation, PV=nRT, we get the volume from the given temperature and pressure. The volume is 19.49 liters.
