Question

50 ml hydrogen takes 10 minutes to diffuse out of a vessel . how long will 10ml of oxygen take to diffuse under similar conditions?

Answer 1

Answer:

12.5minutes

Explanation:

Volume of hydrogen = 50 mL; Time for diffusion (t) = 10 min and volume of oxygen = 10 mL. Rare of diffusion of hydrogen (r1) = 50/10 = 5 mL/min Rate of diffusion of oxygen (r2) = 10/t mL/min Since the molecular mass of hydrogen (M1) = 2 and that of oxygen (M2) = 32,

so, r1/r2=√M2/M1

5/(10/t)=√32/2

5=4*t/10

5*10=4*t

t= 50/4=12.5min
