In our discussion of diffusion, we mentioned that between collisions, a molecule in air travels in a straight line with a constant speed. For a hydrogen molecule in air, this speed is approximately 3000 m/s. If the hydrogen molecule in Problem 42 were moving with this speed and did not collide with any air molecules, how long would it take to travel across the room?

Data From Problem 42
