What pressure is exerted by 2.500 kg of oxygen gas (O2) stored at 22°C in a 40.0-L cylinder? (R = 0.08206 L • atm/K • mol)

47.27 atm

Explanation:

For this problem, you will use PV=nRT as your equation

P =  being found

V= 40 L

n = 78.13 moles

R = 0.082

T= 295.15 K

The set up is:

p (40.0)= (0.082)(78.13)(295.15)

40p=1890.9

p = 47.27 atm
