A solution of palmitic acid in benzine contains 4.24 g of acid per litre.When this solution is dropped on water surface, benzene gets evaporated and palmitic acids forms a unimolecular film on surface. If we wish to cover an area of 500 cm^(2) with unimolecular film, what volume of solution should be used? The area covered by one palmitic acid molecule may be taken as 0.21 nm^(2). Mol.wt.of palmitic acid is 256.
