50 mL of hydrogen takes 10 minutes to diffuse out of a vessel. How long will 40 mL of oxygen take to diffuse out under similar conditions ?

Text Solution

Verified by Experts

The correct Answer is:
B, C
`(r_(H_(2)))/(r_(O_(2)))=sqrt((M_(O_(2)))/(M_(H_(2)))) i.e., (50//10)/(40//t)=sqrt((32)/(2))" or "(5t)/(40)=4" or "t=32 min`.
