Find the rate of diffusion of N 2 compared to O 2 . You may calculate the distance from either end. We chose the end where N 2 was introduced. One gaseous substance can diffuse through another due simply to their random motion. The speed of diffusion of molecules depends on their mass.
Heavy molecules diffuse more slowly than light molecules.
The mathematical relationship is as follows. This distance traveled is proportional to the rate. Obtain a Beral pipet containing concentrated HCl at the hood. Place 2 drops of HCl in well 1 of a 12-well strip. Obtain a Beral pipet containing concentrated NH 3 solution at the hood.
