### Density Calculation ExampleA flask is found to have a mass of 109.80 grams. A liquid is added to a buret, and the initial measurement is found to be 0.25 mL. After liquid has been added to the flask from the buret, the buret reads 13.95 mL. The flask is weighed again, and is found to have a mass of 153.90 grams. What is the density of the liquid in g/mL?#### Steps for Calculation:1. **Initial Mass of Flask:** 109.80 grams2. **Final Mass of Flask (with liquid):** 153.90 grams3. **Mass of Liquid:** 153.90 grams - 109.80 grams = 44.10 grams4. **Initial Volume in Buret:** 0.25 mL5. **Final Volume in Buret:** 13.95 mL6. **Volume of Liquid Dispensed:** $ \text{Volume of Liquid} = 13.95 \text{ mL} - 0.25 \text{ mL} = 13.70 \text{ mL} $#### Density Formula:\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]\[ \text{Density} = \frac{44.10 \text{ grams}}{13.70 \text{ mL}} \]\[ \text{Density} = 3.22 \text{ g/mL} \]### Conclusion:The density of the liquid is **3.22 g/mL**.#### Your Answer:[User to input their answer here]

00 G. You have two objects made of the same substance. Object 1 is a cube with a mass of 246.5 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 123.3 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume is 135.8 mL. Which one of the following is the best reason for the difference between the two calculated densities? A) Different numbers of significant figures were used in each measurement. B) Uncertainty in measurement associated with the equipment. C) Errors in how the density was calculated. D) The units used to measure the densities are not the same. o search a 77°F delete 114 144 5. 6. D.
