What is the average speed (actually the root mean square speed)of a neon atom at 27 °C? A)5.78 m s^-1 B)19.3 m s^-1 C)183 m s^-1 D)609 m s^-1

Question

Quizplus · Accepted Answer

The root mean square speed of a gas molecule can be calculated using the formula $v_{rms} = \sqrt{\frac{3kT}{m}}$, where $k$ is the Boltzmann constant, $T$ is the temperature in Kelvin, and $m$ is the mass of a gas molecule. For neon at 27 °C (or 300 K), the calculation yields a value close to 609 m/s, taking into account the molar mass of neon and converting it to the mass of a single atom for use in the equation.
