ACTIVITY ACTIVITY 2 A Determining the Densities of Solutions 1. Weigh an empty 50-ml graduated cylinder. Record the mass in Data Table 2. 2. Add 5 mL of water (0% sucrose) to the 50-ml graduated cylinder. Use the pipet to add or remove small quantities of liquid so that the water is exactly at the 5-mL mark. 3. Record the Mass of Solution + Graduated Cylinder in Data Table 2. 4. Add more water until the cylinder contains 10 mL...
In the lab, a student fills a dry 50 mL graduated cylinder with 30.0 mL of water. The mass of the water in the graduated cylinder was 30.743 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL.
