What is the total translational kinetic energy of all the molecules of this sample, when itoontains 237 moles of gas? o Previous ® Up s Soulon 2 Check Answer ONext aExil MacBook ProExplanation / Answer
Here ,
let the temperature is T
as kinetic energy = 1.5 * k * T
8.81 *10^-21 = 1.5 * 1.38 *10^-23 * T
solving for T
T = 425 K
the temperature of the sample of gas is 425 K
-----------------------
total translational energy = number of moleules * energy of each molecule
total translational energy = 2.37 * 6.022 *10^23 * 8.81 *10^-21 J
total translational energy = 12573.7 J
the total translational energy is 12573.7 J
