K = the constant for Benzene ( boiling point) is around 2.53.The concentration of Protein in solution can be determined by substituting the molecular weight, extinction coefficient and λ max into a derived form of the Beer - Lambert Law. I = is the van’t Hoff (factor), for Benzene it is considered to be one as it is not an electrolyte. ΔT = is the change in the boiling point ( 1.84 degrees) 80 × 0.023 The benzene’s boiling point is made to rise by around 2.3%.Īctual Benzene’s boiling point = 80 degrees Celsius. Let us analyze how in the section followed:īenzene is used to dissolve the substance ( the unknown one whose molar mass has to be estimated) and it is made to 1.55 % ( mass % that of unknown mixture to Benzene). Usually the most common method of finding Molar mass is by using the formula M = m/n which has been discussed in the earlier section in detail.īy using the colligative properties method we can calculate molar mass without getting mass into picture.
