Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?
