Suppose you have taken a dilute solution of oleic acid in such a way that its concentration becomes$0.01{ \mathrm{cm}}^3$of oleic acid per${\mathrm{cm}}^3$of the solution. Then you make a thin film of this solution (monomolecular thickness) of area$4{ \mathrm{cm}}^2$by considering$100$spherical drops of radius${\left(\frac{3}{40\pi }\right)}^{\frac{1}{3}}\times {10}^{-3} \mathrm{cm}.$Then the thickness of oleic acid layer will be$x\times {10}^{-14} \mathrm{m}$. Where$x$is ________ .
