Suppose you have taken a dilute solution of oleic acid in such a way that its concentration becomes 0.01 cm3 of oleic acid per cm3 of the solution. Then you make a thin film of this solution (monomolecular thickness) of area 4 cm2 by considering 100 spherical drops of radius \((\frac{3}{40\pi})^{\frac 13}\times10^{-3}\) cm. Then the thickness of oleic acid layer will be x × 10–14 m.
Where x is1...........
