Assume that coffee and water have the same density and the same specific heat. 2. a cylinder has a mass of 3262.6 mg. a graduated cylinder filled with water had an initial volume of 1.42 L. when the...
A solid has a mass of 21.15 grams and a density of 1.688 g/mL. The solid is dropped into a graduated cylinder containing water with volume of 15.00 mL. When the solid is dropped into the graduated cylinder, the volume of the water goes up. Using the information given, calculate the final volume of the water in the graduated cylinder.

find density 3. A sample of Co is added to a graduated cylinder containing some water. The volume of the water increases by 10.21 mL. The initial mass of the cylinder and water was 36.56 grams, the final mass of the system (cylinder + water + metal) is 127.02 grams.
A student is determining the density of an unknown metal with a mass of 56.5 g. The student partially fills a graduated cylinder with water and measures the volume of the water by itself as 54.8 mL. The student then adds the metal to the water and measures the new volume as 87.3 mL. What is the density, in g/mL, of the metal?
A 2-liter graduated cylinder initially contains 500ml of water. An irregularly shaped object having a mass of 105gm is submerged into the water. The final volume of the water in the cylinder is 1025ml. Determine the density of the object.
