2. In Avogadro’s Number lab, we used oleic acid to create a monolayer on the surface of water. The oleic acid solution was prepared by dissolving oleic acid in ethanol and it has a concentration of 0.50% by volume. The following parameters of oleic acid will be helpful to solve this question: Molar mass: 282.47 g/mol Density = 0.895 g/mL A) What’s the mass of oleic acid in 1.00 mL of this oleic acid solution? B) How many oleic acid molecules are there in 1.00 mL of this oleic acid solution?
