Expert Solution
Step 1
The rms (average) speed of N2 atoms or molecules at 118oC is to be calculated.
Given:
R = 8.314 kg.m2/K.s2.mol
The root-mean-square speed measures the average speed of particles in a gas, defined as,
Vrms = root mean square (rms)
R = gas constant
T = temperature
M = molar mass in kg/mol
