How many moles of O2 gas are in a 3700 mL container at a pressure of 1.3 at 33 C?

This is what I have so far

P= 1.3
V= 3700
n= ?
R= 0.0821 atm • L / mio • K
T= 33

But I don’t know how to find the answer

Can someone pls help me

watch your units !
P = 1.3 atm ok I suspect
V = 3700 mL = 3.7 Liters !
T in degrees K = degrees C + 273 = 33+273 = 306 K
P V = n R T
n = P V/ (R T) in mols
