When this solution is applied dropwise to the surface of water, benzene evaporates, and palmitic acid forms a monomolecular film. What volume of solution should be taken to cover an area of 500 cm2 with a monolayer (A4 sheet format) if the area occupied by one acid molecule is 21 A2 (1 angstrom A = 1 * 10-8 cm)?
