1. **Problem Statement:** Analyze the distillation data to understand the relationship between temperature and distillation rate, calculate mass of distilled liquid, and interpret refractive index and boiling point data. 2. **Calculate mass of distilled liquid:** - Empty vial + cap mass = 14.79 g - Vial + 5 mL distilled liquid mass = 18.440 g - Mass of 5 mL distilled liquid = 18.440 g - 14.79 g = 3.65 g 3. **Calculate density of distilled liquid:** - Given density = 0.73 g/mL (from data) - Check density using mass and volume: density = mass/volume = 3.65 g / 5 mL = 0.73 g/mL (confirms given density) 4. **Distillation rate vs temperature:** - At 40°C: 12 drops/min, 3 2/3 of vial collected - At 42°C: 15 drops/min - At 45°C: 22 drops/min - At 47°C: 30 drops/min This shows distillation rate increases with temperature. 5. **Refractive index data:** - Temperature = 24.35°C - Refractive index of water (n_water) = 1.402 - Measured refractive index (n_20) = 1.4039 6. **Boiling point data:** - Measured boiling point = 69.4°C - Corrected boiling point = 69.65°C 7. **Summary:** - Mass and density calculations confirm the distilled liquid properties. - Distillation rate increases with temperature. - Refractive index slightly higher than water, indicating purity or composition. - Boiling point correction applied for accuracy. Final answers: - Mass of distilled liquid = 3.65 g - Density = 0.73 g/mL - Boiling point corrected = 69.65°C - Refractive index at 24.35°C = 1.4039
