At constant volume and temperature conditions the rates of diffusion D_(A) and D_(B) of gases A and B having densities rho_(A) and rho_(B) are related by the expression

Answer»

`D_(A)=[D_(B).(rho_(A))/(rho_(B))]^(1//2)`
`D_(A) . [(rho_(B))/(rho_(A))]^(1//2)`
`D_(A)=D_(B)((rho_(A))/(rho_(B)))^(1//2)`
`D_(A)=D_(B)((rho_(B))/(rho_(A)))^(1//2)`

SOLUTION :`(D_(A))/(D_(B))=SQRT((rho_(B))/(rho_(A)))` i.e. `D_(A)=((rho_(B))/(rho_(A)))^(1//2)`
