Question

1. What is the pressure of a 50.0L tank that contains 4.04kg of oxygen, O2, at 23°C? Assume that the Ideal Gas Law is obeyed and use R=0.0821 L atm/mol K (Show ALL Work) 2. What is the pressure of a 50.0L tank that contains 4.04kg of oxygen, O2, at 40°C? Assume that the Ideal Gas Law is obeyed and use R = 0.0821 L atm/mol K (Show ALL Work)

Answer 1

According to ideal gas law PV = nRT p is the pressure V is the volume n is number of moles R = 0.0821 L. atm. mol.kt t is the temperature in Kelvin. mass molar mass

n=4.04x10 g 32 g/nod - 126-25 meles P= HRI P = (126-25 hade ) x ( 0-0821 L-atmmortok) (23 +213)k SOL P = 61-36154 atm 2) n = 4.048103g = 126.25 molu 329 Ind PE HRT P = (12.6 25 had ) X (0-0821 L.atm. med. x-t) (40 +213) K SOL P = 64.8856825 atm.
