###### FREE Expert Solution

We’re being asked to calculate for the root mean square speed of CH4 at 78°C.

When calculating for root mean square speed (μrms), we will use the following equation: µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol

Given: ###### Problem Details
