Answer:

Approx. #0.1*mol# #O_2(g)#

Explanation:

#n=(PV)/(RT)# #=# #((380/760*atm)xx5.00*L)/(0.0821*L*atm*K^-1*mol^-1xx298*K)# #=# #??# #mol#

Note that the answer is in moles of dioxygen, i.e. #O_2# gas. Does the given answer have units of #mol#? If it does not then somewhere I have made a mistake!

Note also that I used the conversion, #"760 mm Hg = 1 atmosphere"#.
