The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.

Answer:
Option a → 111.9 g
Explanation:
The reaction is this:
2KClO₃ → 2KCl + 3O₂
2 moles of chlorate decompose to 2 moles of chloride and 3 moles of oxygen. Ratio is 2:2.
If I use 1.5 moles of chlorate I'll get the same moles of chloride by the decomposition.
Let's convert the moles to mass: 1.5 mol . 74.6 g / 1mol = 11.9 g
