The average kinetic energy of an oxygen molecule can be calculated using the equation for kinetic energy, which is given as Ek = (3/2)kBT, where kB is the Boltzmann constant, T is the temperature of the gas, and Ek is the average kinetic energy. In this case, the temperature is 330°C, so using the conversion of 273°C = 1K, the temperature of the gas is 603K. Plugging the values into the equation, the average kinetic energy of an oxygen molecule is 2.665 x 10-21J.
