Hydrogen chloride gas (hcl) diffuses 1.8 times faster than an unknown gas. determine the molar mass of the unknown gas. show your work or explain your answer, giving specific values used to determine the answer.

The molar mass of the unknown gas is 118.26 g/mol.

Explanation:

Graham's law: The rate of diffusion of gaseous substance in inversely proportional to the  square root of its molecular mass.

Rate of the unknown gas ,R=R

Rate of the HCl gas,R' = 1.8R

Molar mass of unknown gas = M

Molar mass of the HCl gas = 36.5 g/mol

According to Graham's law:

The molar mass of the unknown gas is 118.26 g/mol.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
