1. Solving a chemistry problem

496. When acetic acid was distributed between carbon tetrachloride and water, the following concentrations were obtained:
in CCl4, g/l 2.92 3.63 7.25 10.7 14.1
in water, g/l 48.7 54.2 76.4 93.0 107.0
Acetic acid in aqueous solution has a normal molecular weight. Derive a mathematical expression for the distribution law for this system and calculate the molecular mass of acetic acid in carbon tetrachloride.
