87. Solving a chemistry problem
124. From 5.19 * 10-5 g of palmitic acid (C15H31COOH, insoluble in water), a dilute solution was prepared in benzene and applied to the surface of the water. After the evaporation of benzene, it was possible to compress the remaining film to an area of 265 cm2. Calculate the area occupied by one molecule in such a film.
