0.27 g of a long chain fatty acid was dissolved in 100 cm³ of hexane. 10 mL of this solution was added dropwise to the surface of water in a round watch glass. Hexane evaporates and a monolayer is formed. The distance from edge to centre of the watch glass is 10 cm. What is the height of the monolayer ?[Density of fatty acid = 0.9 g cm^-3, π=3]

• 10^-6 m

• 10^-2 m

• 10^-4 m

• 10^-8 m

• (k₁ - k₂)[A]

• $\left(\frac{{\mathrm{k}}_1}{{\mathrm{k}}_2}\right)\left[\mathrm{A}\right]$

• k₁k₂[A]
