Suppose you have taken a dilute solution of oleic acid in such a way that its concentration becomes `0.01 cm^(3)` of oleic acid per `cm^(3)` of the solution. Then you make a thin film of this solution (monomolecular thickness) of area 4 `cm^(2)` by considering 100 spherical drops of radius `((3)/(40pi))^((1)/(3))xx10^(-3)` cm. Then the thickness of oleic acid layer will be `x xx10^(-14)` m. Where x is ___________.
