The equation for density is mass/volume. Make sure your units match what is given in the problem.
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.
