In 100 seconds, 300 mL of nitrogen diffuse through a porous partition. How long will 400 mL of `CO_2` take to diffuse through the same partition under similar conditions ?

Two g of hydrogen diffuse from a container in 10 minute. How many gram of oxygen would diffuse through the same container in the same time under similar conditions:

Through a given partition 7.5 liters of carbon dioxide diffuse in certain time. Calculate the volume of oxygen that diffuse through the same partition under the same conditions. (Atomic weight of C = 12, O = 16)

The molecular weight of a gas which diffuses through a porous plug of 1/6th of the speed of hydrogen under identical conditions is :

3.2 g oxygen is diffused in 10 minutes. In similar condition 2.8 g nitrogen will diffuse in :

In an experiment , 100 mL of H_2 takes 2.5 seconds and 100mL of an unknown gas take 20seconds to penetrate through a porous surface. What is the density of unknown gas with respect to hydrogen ?

Under certain conditions 6.7 mL of sulphur dioxide diffuse in 5.5 minutes. Under the same conditions 66.8 Ml of another gas diffuse in 4 minutes. Calculate the molecular weight of the other gas if that of sulphur dioxide is 64.

A current of 1.70 A is passed through 300.0 mL of 0.160 M solution of ZnSO_(4) for 230s with a current efficiency of 90 per cent. Find out the molarity of Zn^(2+) after the deposition of zinc. Assume the volume of the solution to remain constant during electrolysis.

How long a current of 2A is to be applied through a solution of AgNO_3 to coat a material of metal surface 100 cm^2 area and 0.005 mm thickness ? (density of Ag=10.5 gm//cm^3 , & atomic mass = 108)
