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 65.8 point of solvent, °C Freezing point depression constant (kf 2.49 of solvent, °C m1 mass of solute, g 0.250 mass of solvent, g 2.100 molar mass of solute, g mol1 148.21
