Question

if 50ml of h2diffuse through a hole in 20 second then calculate the volumy of o2 gas diffuse through the same hole in 30sec.....plzzzzzz solve this it's urgent

Answer 1

Rate of diffusion of gases is given by the formula :

rate 1 / rate 2 = √ M2 / M1

Where R1 and R2 is rate of diffusion of two gases , M1 and M2 is corresponding molecular weight(MW).

So rate of diffusion of Hydrogen(MW=2) and oxygen(MW=32) can be calculated as:

Rate H2 / Rate O2 = √ 32 / √2

= √16

= 4

It means Hydrogen diffuse 4 times faster than Oxygen.

Now 50 ml. of H2 is diffise in 20 min.

∴ 40 ml. of H2 will diffuse in 20/50 x 40 = 16 min.

So 40 ml. of O2 will takes time = 16 x 4 = 64 min.
