Estimation Of Very Small Distances: Size Of A Molecule

A simple method for estimating the molecular size of oleic acid. Oleic acid is a soapy liquid with large molecular size of the order of 10⁻⁹ m. We dissolve 1 cm³ of oleic acid in alcohol to make a solution of 20 cm³, Then we take 1 cm³ of this solution and dilute it to […]
