Speed (rms) = sqrt 3KT/m, where: K = Boltzmann's costant = 1.38*10^-23 joule/K; T = temperature in Kelvin degrees = 273 - 63 = 210 K; m = 44 * 1.672*10^-27 Kg; 1.672*10^-27 Kg (good approximation) is the weight of a single a. m. u. (atomic mass unit); 44 is molecular weight of CO2. Molecular Speed (CO2) = sqrt 3*1.38*10^-23*210/44*1.672*10^-27 = 344 m/sec. Excuse me for some imperfection in my language, I am from South Italy.
