We can use the ideal gas law to solve for the volume of the compressed air: PV = nRT where P = 100 atm, V = 40 L, n = 200 mol, R is the gas constant, and T is the temperature. Solving for T: T = PV/nR = (100 atm * 40 L)/(200 mol * 8.314 J/(mol K)) = 240 K Now we can use the same equation to solve for the volume occupied by O₂ at 1 atm and 298 K: V' = nRT/P = (1 atm * 40 L)/(200 mol * 0.0821 L atm/(mol K) * 298 K) = 1.34 L Therefore, the answer is B) 1.34 L.
