Question

The densities of hydrogen and oxygen are 0.09 and 1.44 g `L^(-1)`. If the rate of diffusion of hydrogen is 1 then that of oxygen in the same units will be
A. 4
B. `1//4`
C. 16
D. `1//16`

Answer 1

Correct Answer - B
`r_(O)=r_(H)sqrt((d_(H))/(d_(O)))=1 sqrt((0.09)/(1.44))=sqrt((1)/(16))=(1)/(4)`
