Question #167700

The rate of diffusion of a gas Z is twice (IV) oxide. [SOÂ² =64]. What is the molecular mass of Z ?

Expert's answer

Rate of SO2= R

Rate of Z = 2R

Rate of Z/Rate of SO2 = âˆšMolar mass of SO2/ âˆšmolar mass of Z

2R/R = âˆš64/âˆšZ

âˆšZ = (R x âˆš64)/ 2R

âˆšZ = 4

Z= 4^2 = 16

Hence, the molecular mass of Z is 16g/mol
