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

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.
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.
