A)5)78 m/s
B)19.3 m/s
C)183 m/s
D)609 m/s

Quizplus · Accepted Answer

The root-mean-square speed of a gas molecule is given by the formula: v_rms = sqrt((3kT)/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a molecule. At 27°C (300K), the calculation for neon gives approximately 609 m/s.
