Determining the mass of a substance

I keep coming up with .05grams. Apparently the wrong answer. The question is: What mass of oxgen gas will occupy 450.mL at 145mmHg and 62.5 degrees Celcius?
I am also having trouble with finging the volume in liters of 52.0g of CO2 at 410mmHg and 99.0 degrees Celcius. I have used the n=PV/RT formula for the mass and V=PnRT for the volume and it is not working. Help!
