Mass absorption coefficient of a solution containing g of KI and g of water should be calculated.
Mass absorption coefficient ( ) is the absorption cross section per unit mass (units are Mass absorption coefficient is independent of chemical and physical nature of elements.
Mass absorption coefficient ( ) of a sample can be calculated by adding the contributions of the mass absorption coefficients of each element present in the sample.
Contribution of “element A” to the mass absorption coefficient of a sample can be written as
Therefore, the mass absorption coefficient ( ) of a sample can be written as,
In order to calculate mass fractions of each element in a sample, the atomic mass of each element and the molar mass of each compound should be known.
Transmitted fraction of the radiation when the Mo source radiation is passed through a layer of the solution should be calculated.
Beer’s law can be written as follows, in which, mass absorption coefficient ( ) is included.
Transmittance (T) of a medium is the fraction of incident radiation transmitted by the medium.
Therefore, transmittance can be rewritten as:
