Im trying to figure out the answer

Question

Now consider whether this relationship holds true for a process more complex than simple gas speed: diffusion. Use the molar masses of NH3 and HCl to calculate the predicted ratio of their molecules’ speeds.
NH3: 17.03
HCl: 36.46(what would the answer be to this. I am completely lost)

Answer 1

According to Graham's law, the rate of diffusion is inverse proportional to the square root of the masses.

 

NH3 molar mass = 17.03

HCL molar mass = 36.56   The expected ratio of their molecule speeds is (36.56/17.03) ^ 0.5 =  1.465.
