**Density of 10% Aqueous Solution of Sodium Chloride, NaCl**In this educational exercise, a student conducted an experiment to determine the density of a 10% aqueous solution of sodium chloride (NaCl). Listed below are the collected data. The data is to be filled in appropriately along with units for clarity and understanding.**Table: Density of 10% Aqueous Solution of Sodium Chloride, NaCl**| | Trial 1 | Trial 2 ||---------------------------------|---------------------------|---------------------------|| Mass of empty graduated cylinder| 19.87 g | 16.35 g || Mass of cylinder + sodium chloride solution | 30.65 g | 31.25 g || Mass of sodium chloride solution| | || Volume of sodium chloride solution | 10.0 mL | 15.0 mL || Density of solution | | || Average density | | |**Explanation of Columns:**- **Mass of empty graduated cylinder:** The weight of the empty container before any solution is added. - **Mass of cylinder + sodium chloride solution:** The total weight after the sodium chloride solution is added to the cylinder.- **Mass of sodium chloride solution:** This is calculated by subtracting the mass of the empty graduated cylinder from the mass of the cylinder with the solution.- **Volume of sodium chloride solution:** The volume of the solution added to the cylinder.- **Density of solution:** This is determined using the formula: \[ \text{Density} = \frac{\text{Mass of sodium chloride solution}}{\text{Volume of sodium chloride solution}} \]- **Average density:** This is the mean of the densities calculated from both trials.**Calculations:**1. **Trial 1:** - Mass of sodium chloride solution: \[ 30.65 \, \text{g} - 19.87 \, \text{g} = 10.78 \, \text{g} \] - Density of solution: \[ \frac{10.78 \, \text{g}}{10.0 \, \text{mL}} = 1.078 \, \text{g/mL} \]2. **Trial 2:** - Mass of sodium

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 nust 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 determnination of the melting point of the solution.
