Let gas 1 be H2. Gas 2 is O2

 

(R1/R2)=(P1/P2)*(sqroot(m2/m1))=(n1/n2)

 

=> (P1/P2)*(sqroot(m2/m1))=(n1/n2)

=> (1/1.5)*(sqroot(32/2))=(2/n2)

=> (2/3)*(4)=(2/n2)

=> (n2)= 8/6   moles = 4/3 moles

=> Weight = 32*4/3 = 128/3 grams

 

 

R1 - Rate of diffusion of gas 1.

M1 - Molecular Weight of gas 1.

n1 - No. of moles of gas 1.
