Problem- Suppose that you have a sample which is a mixed monolayer of C540 and C60 molecules assembled on a flat surface (10 cm2) . This monolayer is a densely-packed monolayer, and contains 10% of C540 molecules. Assume that all C60 molecules can be desorbed into a solution (10 mL) while keeping the C540 molecules intact and in place, estimate the concentration of C60 molecules desorbed into a solution (in # molecules per mL).

Solve the above problem in detail no word count
