```							Calculate the root-mean-square velocity of gas molecules from the temperature of gas using the following equation:Vrms = (3RT/M)^(1/2)Make sure to use units consistently.For example,if the molecular weight is taken to be in grams per mole andthe value of the ideal gas constant is in joules per mole per degree Kelvin, andthe temperature is in degrees Kelvin, then the ideal gas constant is in joules per mole-degree Kelvin, and the velocity is in meters per second.
