4. A gas diffuses 1.27 times as rapidly as Ch under the same condition

1.	4. A gas diffuses 1.27 times as rapidly as Ch under the same conditions of temperature andpressure. Answer the following:() is the gas heavier or lighter than Ch.(i) What is the ratio of the molecular mass of the gas to that of Cl?
Answer» According to Graham' s Law , rate of diffusion is inversely proportional to the square root of its molecular weight. therefore...... Let m1be the mass of the unknown gasm2is the mass of Cl2r1= rate of diffusion of the unknown gasr2= rate of diffusion of Cl2 (i) Hence, m1 < m2=> Cl2 is heavier than unknown gas Now refer to the attachment...

Answer»

According to Graham' s Law , rate of diffusion is inversely proportional to the square root of its molecular weight.

therefore......

Let m1be the mass of the unknown gasm2is the mass of Cl2r1= rate of diffusion of the unknown gasr2= rate of diffusion of Cl2

(i) Hence, m1 < m2=> Cl2 is heavier than unknown gas
