Answer:

68.4 litres

Explanation:

Assuming all oxygen atoms here are O-16 and that 1 mol of any gas at room temperature and pressure is 24#dm^3#,

#M_r=("mass of gas")/(A_r)#, where #M_r# is molar mass and #A_r# is atomic mass

#M_r=45.6/(16*2)=2.85 mol# (bearing in mind oxygen gas in in the #O_2# state)

Therefore, the volume of oxygen is:

#V_(O_2)=2.85 mol*24dm^3=68.4dm^3=68.4 l#
