Question

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, V_rms, 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?

"Please read my complaint about the two previous answers given to this same question. I must be able to read the answer clearly so that I can compare it with my own work. I have asked previously if it would be possible for the expert answer to be typed or at least be clearly written in a legible holograph. Thank you "
