# Problem: Calculate the root mean square velocities of CH4(g) and N2(g) molecules at 273 K and 546 K.

###### FREE Expert Solution

root mean square speed (Crms):

${\mathbf{C}}_{\mathbf{rms}}\mathbf{=}\sqrt{\frac{\mathbf{3}\mathbf{RT}}{\mathbf{M}}}$

µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol

MM of CH4 → 16.04 g/mol

MM of N2 → 28 g/mol
