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