Which gas law would you use for the following problem: What pressure is required to hold 8.0 moles of oxygen gas in an 8.0 L con
emmainna [20.7K]

Answer:

Ideal Gas Law ( PV = nRT)

Explanation:

Using the Ideal Gas Law, we have; PV = nRT

Where P= Pressure = ?

            V= Volume = 8.0 L

            n =  moles = 8.0

            R =  Gas constant = 0.0821 L.atm/mol/K

            T =  80° c + 273 =  353.15K

Therefore Pressure would be;  P = nRT/ V =  8 x 0.0821 x 353.15 / 8 = 28.9atm
