Find the rms speed of the molecules of a sample of n2 (diatomic nitrogen) gas at a temperature of 35.9â°c.

The root mean square velocity (RMS velocity) is a method to find a single velocity value for the particles. The average velocity of gas particles in a mixture is found using the root mean square velocity formula:

 μrms = sqrt (3RT/M)

Where,

R = universal gas constant = 8.3145 (kg·m^2/s^2)/K·mol

T = temperature = 35.9 ˚C = 309.05 K

M = molar mass = 28 * 10^-3 kg / mol

Substituting the given values into the equation:

μrms = sqrt [(3 * 8.3145 (kg·m^2/s^2) /K·mol) * (309.05 K) / (28 * 10^-3 kg / mol))]

μrms = sqrt (275,313.8813 m^2)

μrms = 524.7 m / s                     (ANSWER)

the answer is a. co2, this would be colder than the : )
