A solution of palmitic acid in benzene contains 4.24g of acid per litre. When this solution is dropped on a surface, benzene gets evaporated and palmitic acid forms a unimolecular film on the surface. If we wish to cover an area of 500 cm² with unimolecular film, what volume of solution should be used? The area covered by one palmitic acid molecule may be taken as 0.21 nm².Mol. Weight of palmitic acid= 256
