Consider a given volume of carbon dioxide gas at room temperature (20.00C). (Molar Mass of Carbon dioxide is: 44.0 x 10-3 kg mol-1 J). (i). Calculate the root-mean-square Speed, Vrms, of a molecule of the gas? The answer must be given in scientific notation and specified to an appropriate number of scientific figures. (ii). At what temperature would the root-mean-square-speed be half of that at room temperature?
