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

Correct answer

64

Step-by-step solution

If 40 m l O 2 will diffuse in t min. then. r O 2 = 40 t r H 2 = 50 20 r O 2 = r H 2 M H 2 M O 2 = 50 20 2 32 = 50 20 . 1 4 40 t = 50 80 ∴ t = 40 × 80 50 = 64 m i n .
