Report the actual mass of H2O delivered to the flask. (Density of water = 1g/mL at 25°C.) (Poured 100mL of water in flask)
An empty vial has a mass of 67.77 g. If the vial has a mass of 244.56 g when completely filled with liquid carbon terachloride (d = 1.59 g/cm3), what is the volume of the vial?
A metal rod has a mass of 17.62 g. A graduated cylinder contains 28.9 mL of water. The metal rod is added to the cylinder. The final water level in the cylinder is 35.1 mL. What is the density of the metal rod?
