If the air contains 21% oxygen, how many molecules of O2 in the lungs and contain 37degree 1.1atm Cel?

A couple half of the lungs a volume of 5.5 L. I love the setting of heart Help! the answer is 1.4 x 10 ^ 23, but I can not understand why the establishment did not use 8.314 0.0821

At STP, 1 mol of gas occupies 22.4 liters. 21% O2 at 1.1 atm and 37 degrees Celsius = 310 K So, using the equation PV = nRT and solve for n = PV / RT plug in the values: P = 0.23 atm V = 5.5L, T = 310 K, R = 8.314 J / mol K, J 1 = 9.8 x 10 ^ – 3 atm liter. N = 1.265 liters atm/310 K x 8.314 J / K = 0.0005 atm mol nm L / J 1 = 9.8 J x 10 ^ -3 atm n = 0.05 moles per liter so there are 3 x 10 ^ 22 molecules of oxygen in the lungs.
