A sealed cubical container 21.0 cm on a side contains a gas with three times Avogadro's number of krypton atoms at a temperature of 24.0C. HINT (a) Find the internal energy (in ]) of the gas. 11106.31 J (b) The total translational kinetic energy (in ]) of the gas. 11149.74 J (c) Calculate the average kinetic energy (in ]) per atom. 6.17e-21 J (d) Use P = 2 N 1 3 V 2 mv2 ) to calculate the gas pressure (in Pa). X Pa (e) Calculate the gas pressure (in Pa) using the ideal gas law (PV = nRT). 422915.50 X Pa
