Michael Patino 01115539 Chem 1122-Trupta Experiment 3- Understanding the Basics: The Mole and Counting Atoms Objective / Aim of the lab- The objective of this lab is to allow the experimenter to explain why the mole is a useful unit in chemistry. In chemistry, the mole is used countless of times, and this lab emphasized on its use giving us the opportunity to practice it. This is determined by finding the mass of a big amount of items and narrowing it to one of the item to find out how many items are present. It made sure we were able to count things using mass. The experiment also stressed converting between Grams  Moles  Atoms/Molecules. Using the skills from the previous lab, where we learned to correctly use the significant figures was crucially important. Introduction/background information- In Chemistry, the emphasis on working with extremely small things, such as atoms and molecules, which are usually too small to count by conventional methods, is highly stressed. Atoms are made of electrons, neutrons, and protons. In an Isotope, the element has a plus or
