Finding Avogadro's Number?
The cetyl alcohol molecules are cylindrical with the diameter of the cylinder equal to one fifth of the length. Assume the long axis of the cylinder is perpendicular to the water surface. The Medicin dropper used in this experiment was calibrated at 81 drops per milliliter. Using the above data and model, calculate Avogadro's number. (Hint: the volume of a cylinder is v=(Pi)(r^2)(h), r = radius, h = height, and r = (t/10).)
Sorry to ask this, but i've been working on this one problem since Thursday of last week and try as I might, I cannot figure it out. Please help me!
