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?

Assume that you have 40000 molecules of carbon dioxide in a box at a temperature of 300 K. Also, imagine if the speed distribution of the molecules is governed by the following function N(v) = Ave(-Mv^2/2RT) instead of a Boltzmann distribution N(v) = Av2e(-Mv^2/2RT) Normalize this function to solve for A. Also, solve for the vrms of the carbon dioxide gas. [Use .044 kg/mol for the molar mass of carbon dioxide] Group of answer choices a) A = .706, Vrms = 348.25...
