Question 130 of 192

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 ${\left(\dfrac{3}{40\pi }\right)}^{\dfrac{1}{3}}\times {10}^{-3}cm.$ Then the thickness of oleic acid layer will be $x\times {10}^{-14}m$. Where $x$ is ________ .
