To calculate the molar volume of a gas at STP you can use the ideal gas law equation, PV=nRT.
Since the molar volume of oxygen represents the volume occupied by 1 mole of oxygen at STP conditions, the ideal gas law equation can be written as
PV=1⋅RT=RT
Now, STP conditions imply a pressure of 100 kPa and temperature of -273.15 K. Plug these values into the equation and you'll get
V=RTP=0.082057atm⋅Lmol⋅K⋅273.15K100101.325atm=22.71
