Answer 1

Answer:

The answer is 14.14 dm^3

Given: Volume of SO2=20 dm^3 Time taken for diffusion by SO2= 60 sec, Time taken for diffusion by O2= 30 sec.

To find: Volume of O2

Solution:

Let the volume of O2 be V

Rate of diffusion of SO2=20/60=1/3

Rate of diffusion of O2=V/30

We know, r1/r2=root of m2/root of m1 (where m1 and m2 are the molecular masses)

1/3/V/30 =square root of 32/square root of 64

1/3* root 2 =V/30

10*root 2 =V

10*1.414 =V

14.14 dm^3 =V

i.e Volume of O2 is 14.14 dm^3.
