What is the average speed vavg of the molecules in the gas? express your answer numerically to three significant digits?

In order to determine the velocity of gas molecules, it would not be unreasonable to measure the average velocity, vavg, of the gas molecules. However, the molecules of gas are constantly moving in completely random directions and this results in the average velocity being equal to 0 m/s.
