### Experiment: Calculating the Density of a 10% Aqueous Solution of Sodium Chloride (NaCl) #### Objective: To determine the density of a 10% aqueous solution of sodium chloride using experimental data. #### Procedure: A student performed an experiment to calculate the density of a 10% aqueous solution of sodium chloride, NaCl. The student collected the following data for two trials: #### Data Collected: - **Trial 1:** - Mass of empty graduated cylinder: 19.87 g - Mass of cylinder + sodium chloride solution: 30.65 g - Volume of sodium chloride solution: 10.0 mL - **Trial 2:** - Mass of empty graduated cylinder: 16.35 g - Mass of cylinder + sodium chloride solution: 31.25 g - Volume of sodium chloride solution: 15.0 mL #### Results Table: The table summarizes the data collected and outlines the subsequent steps to calculate the density. **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 | (calculated) | (calculated) | | Volume of sodium chloride solution | 10.0 mL | 15.0 mL | | Density of solution | (calculated) | (calculated) | | Average density | (calculated) | (calculated) | #### Calculations: 1. **Mass of Sodium Chloride Solution:** - **Trial 1:** \( 30.65 \, \text{g} - 19.87 \, \text{g} = 10.78 \, \text{g} \) - **Trial 2:** \( 31.25 \, \text{g} - 16.35 \, \text{g} = 14.90 \, \text{g} \) 2. **Density of Solution:** - **Formula:** \( \text{Density} = \frac{\text{Mass}}
