In the preparation of Fe3O4 NPs, 2 mmol of Fe(acac)3 precursor was reacted with 6 mmol oleic acid (OA). Assume that the nuclei are monodisperse spheres of Fe3O4 (density 5.12 g.cm-3), which are formed in 100% yield at 0.8 nm in diameter, and given a maximum surface coverage of 22 2 (22x10-20 m2) per molecule of OA.

Calculate: (i) the number of moles of OA required to form a perfect monolayer on all the nuclei formed (ii) the number of monolayer equivalents that were present
