Procedures: Part A: Measure the inner diameter of the Petri dish. Weigh the dish then add the beads at one layer thick to the Petri Dish. Weigh the dish again with the beads inside, and repeat this procedure to find the average. Part B: use clean tray and pour 1L of water into the tray. Squeeze a small amount of powder onto the tray, creating a thin film. Then add one drop of acid onto the tray. Measure the diameter of the resulting oil film at four different angles and take the average. Rinse and repeat experiment 3 times. Next obtain a volumetric flask and fill it with approximately 25ml of water; measure the weight of the flask then the weight of the flask plus the water. Drop 15 drops of oil into water and record weight. Use this to obtain Avogadro’s number by the use of density.
