A solution of palmitic acid (M=256) in benzene contains 4.24 g acid per litre. When this solution is dropped on the water surface, benzene evaporates and palmitic acid forms monomolecular film of the solid type. If we wish to cover an area of 500 `cm^(2)` with a monolayer, what volume of solution should be used ? The area occupied by one palmitic acid molecule may be taken to be `21 xx 10^(-20) m^(2)`

Palmitic acid is

A solution of palmitic acid (Molar mass = 256) in Benzene contain 5.12 g of acid per litre of solution. When this solution is dropped on a water surface, the Benzene evaporates and acid forms a monolayer film of solid type. If 500 cm^(2) are is to be covered by a monolayer, then find X, where X = (V)/(100) , when V is volume required of solution. The area covered by 1 molecule = 0.2 nm^(2) .

A solution of stearic acid (C_(18)H_(36)O_(2),M=284) in benzene contains 1.42 gm acid per L. When this solution (100 L) is dropped on surface, C_(6)H_(6) gets eveporated and acid forms a unimolecular layer on the surface. If it covers an area 6020 cm^(2) with unimolecular film, find the area covered by one molecule of acid.
