Lab 4. Molarity: What Is the Mathematical Relationship Between the Moles of a Solute, the Volume of the Solvent, and the Molarity of an Aqueous Solution?Introduction Most of the matter around us is a mixture of pure substances. The main characteristic of a mixture is its variable composition. For example, a sports drink is a mixture of many substances, such as sugar and salt, with the proportions of substances varying depending on the type of sports drink. Mixtures can be classified as either homogeneous or heterogeneous. Homogeneous mixtures have parts that are not visually distinguishable, whereas heterogeneous mixtures have parts that can be distinguished visually. A homogeneous mixture is often called a solution. A sports drink therefore is a solution. Much of the chemistry that affects us occurs among substances dissolved in water. It is therefore important to understand the nature of solutions in which water is the dissolving medium or the solvent. This type of solution is called an aqueous solution. An aqueous solution contains one or more chemicals (or solutes) dissolved in water (the solvent). The most common way to describe the concentration of a solute in an aqueous solution is to use a unit of measurement called molarity. In this lab investigation, you will explore the relationship between moles of solute, volume of solvent, and molarity. Your TaskUse a computer simulation to determine the mathematical relationship between moles of solute, volume of solvent, and molarity. Once you have determined this relationship, you should be able to set up various functions that will allow you to accurately predict •the molarity of a solution given the moles of solute and solvent volume,•the moles of solute given the molarity of the solution and the volume of the solvent, and •the volume of the solvent given the molarity of the solution and the moles of the solute. The guiding question of this investigation is, What is the mathematical relationship between the moles of a solute, the volume of the solvent, and the molarity of an aqueous solution?MaterialsYou will use an online simulation called Molarity to conduct your investigation. You can access the simulation by going to the following website: http://phet. colorado. edu/en/simulation/molarity. Safety PrecautionsFollow all normal lab safety rules. Investigation Proposal Required? Yes  NoGetting StartedThe first step in developing your mathematical function is to determine how moles of solute and volume of the solvent are related to the molarity of a solution. The Molarity simulation (see screenshot in Figure L4.1) allows you to mix different moles of solute in different volumes of water (the solvent). It then provides a measure of the molarity of the resulting aqueous solution. Before you start using the simulation, you must determine what type of data you will need to collect, how you will collect the data, and how you will analyze the data to answer the guiding question. To determine what type of data you need to collect, think about the following questions:•What type of observations will you need to record during your investigation?•When will you need to make these observations?To determine how you will collect the data, think about the following questions:•What types of comparisons will you need to make? •How will you keep track of the data you collect and how will you organize it?
