Q 9 How you can measure the size of molecule of a liquid (oleic acid).
​

Answer 1

Answer:

To this, we add one drop of oleic acid. The drop quickly spreads into a thin, large circular film of molecular thickness. This is the oleic acid molecules standing on their hydrophilic ends. We can measure the diameter of this circle using which we can calculate the area 'A'.
