Question

5 moles of o, gas diffused through a porous partition in 30 seconds. How many moles of H2 gas can diffuse through the partition in 60
seconds under the same condition of pressure
and temperature?
​

Answer 1

Answer:

20 moles

Explanation:

Let the number of moles of H2 bas diffused = x

then by formula,

Rate of diffusion of oxygen / rate of diffusion of hydrogen

=

$\sqrt{(mass \: of \: hydrogen) \div (mass \: of \: oxygen)}$

so,

so, rate of diffusion of O2 = 5/30 = 1/6

and rate of diffusion of H2 = x/60

so rate of diffusion of O2÷ rate of diffusion of H2

= 1/6 ÷ x/60 = 10/x

Thus 10/x =

$\sqrt{mass \: of \: hydrogen \: \div \: mass \: of \: oxygen}$

so, 100/ x ² = 2/ 32

x²= 100× 32 /2

x²= 1600

x= 40 moles

so , 40 moles of hydrogen is diffused.
