3. A 100-ml. graduated cylinder is filled with water to a volume of 50,0 mL.. A piece of copper metal (d = 8.92 g/mL.) with a mass of 23.9 g is added to the water in the cylinder. To what level will the water rise after the copper has been added? 4. A student finds the mass of an empty flask to be 25.631 g. After the flask is filled to the halfway mark with distilled water at 22.0 °C (d= 0.99777 g/cm³), the mass of the flask and water is 35.432 g. The student then forms a solution by adding some sodium hydroxide pellets and stirring the flask's contents until the pellets dissolve. The mass of the flask, and its contents, is now 36.138 g, but the volume remains the same, still at the halfway mark. What is the density of the sodium hydroxide solution? 5. An empty flask (m = 223.40 g) is filled to the brim with water (d = 0.99777 g/cm³) and the mass of the flask and water is determined to be 311.62 g. 10.00 g of zinc pellets (d= 7.140 g/cm³) are added to a flask, and the water that is displaced is wiped from the flask. What is the mass of the flask and its contents? Empty flask (223.40 g). Flask + water (311.62 g) (Displaced water) Flask + zinc pellets + remaining water (mass=? g) 3.
