Anna Divi, a young and ambitious researcher, is planning to put up her very own research laboratory. However, she does not have the funds for this to happen. She then approached Alan Read, CEO of a well-known funding agency, to help her pursue her dream laboratory. Before Alan considers Anna's proposal, Anna must perform an experiment on determining the melting point of solutions. She must have an accurate result with a percent error not greater than 3%. The data on the experiment is given below. Help Anna achieve her goals by performing the necessary calculations below. Table 1. Data on the determination of the melting point of the solution. Parameters Values Theoretical freezing point of solvent, °C 65.8 Freezing point depression constant (k) 2.49 of solvent, °C m1 mass of solute, g 0.250 mass of solvent,g 2.100 molar mass of solute, g 148.21 mol1

A traditional way of determining the concentration of alcohol in alcoholic beverages is by measuring thedensity of the solution, since these two characteristics of the solution (density and % alcohol) arerelated. This is a convenient determination method because it is low cost and can be done quickly. Thisis why customs officials sometimes use density measurements to classify alcoholic beverages and spirits.In the stockroom, you will find a variety of reagents including two alcoholic beverages. Design andperform an experiment to classify each of the two alcoholic beverages into one of the following fivecategories of alcohol strength (based on % v/v) defined by the Canadian importation laws:1. Less than 0.5% by volume2. 0.5% - 1.2%3. 1.2% - 7.0%4. 7.0% - 22.9%5. More than 22.9% by volume Pre-Lab Questions1.
