1.Find the total translational kinetic energy of 0.5 L of oxygen gas held at a temperature of 0°C and a pressure of 1.3 atm. 2. R = 8.314 PV=nRT PV=NkT K=(.5*m*v^2) Translational Kinetic Energy = T=(2/3)(1/k)[(.5)mv^2] 3. The problem says to express the total translational kinetic energy of the oxygen gas by combining the expression for the translational kinetic energy and the ideal-gas law to obtain an expression for K in terms of the pressure and volume of the gas. I tried subsitituting T= PV/nR to T=(2/3)(1/k)[(.5)mv^2] but I am not sure if I am on the right track.
