I'll do my best to help.
You know the ideal gas equation right?
PV=nRT
P=pressure (atm)
V=volume (L)
n=number moles of gas
R=gas constant=.08206 (atm L/mol K)
T=Temperature (Kelvin)
So convert the temperature to kelvin.
Then convert the mass of O2 gas to moles (In one mole of O2, there are 31.9988 grams of O2, so convert the given mass to grams and then to moles of O2). Plug stuff in... solve for P.
Do you still need more help?
