$50 m l$ of hydrogen diffuses out through a small hole from a vessel in $20$ minutes. Calculate the time (in minutes) needed for $40 m l$ of oxygen to diffuse out

Answer:

64.00

Solution:

If $40 m l O_{2}$ will diffuse in t min. then. $r_{O_{2}} = \frac{40}{t}$

$r_{H_{2}} = \frac{50}{20}$

$r_{O_{2}} = r_{H_{2}} \sqrt{\frac{M_{H_{2}}}{M_{O_{2}}}} = \frac{50}{20} \sqrt{\frac{2}{32}} = \frac{50}{20} . \frac{1}{4}$

$\frac{40}{t} = \frac{50}{80} ∴ t = \frac{40 \times 80}{50} = 64 m i n .$
