If 100cm³ of oxygen pass through a porous plug is 50 seconds, the time taken for the same volume of hydrogen to pass through the same porous plug is? [O = 16, H = 1]

10.0s

12.5s

17.7s

32.0s

Correct answer is B

Rate of diffusion $\frac{\alpha_1}{Density}$ or $\frac{1}{\sqrt{Mm}}$

Rate = $\frac{1}{time}$

$\frac{1}{time}$ $\frac{\alpha_1}{Density}$ or $\frac{1}{\sqrt{Molarmass}}$

Time $\alpha \sqrt{Density}$ or $\sqrt{Molarmass}$

At constant volume of 100cm³

$\frac{t_{o2}}{\sqrt{Mn_{o2}}}$ = $\frac{t_{n2}}{\sqrt{1 \times 2}}$

$\frac{50}{4 \sqrt{2}}$ = $\frac{t_{n2}}{\sqrt{2}}$

t_n2= 12.5s
