The film may or mat not be one molecule thick, it depends on whether it
"spreads". It is possible to get good agreement with Avogadro's Number if the
film spreads to what is assumed to be a monomolecular layer. Sometimes
surface tension prevents the film from spreading and the agreement with
Avogadro's number is poor.
