Question

50 ml of hydrogen diffuses out through a small hole of a vessels in 20 min the time taken by 40 ml of oxygen to diffuses out is

Answer 1

 If 40 ml  

O2

 will diffuse in t min. then. 

rO2=40t

                   

rH=5020

 Þ  

rO=rH2MH2MO2−−−−−√=5020232−−−√=5020.14

                                

40t=5080∴t=40×8050=60

min.
