When performing this experiment, a student discovered that the weighed metal sample was too wide to fit into the graduated cylinder. The student pounded the corners of the sample until it fit into the cylinder. Would this procedural change affect the density calculation? Briefly explain. After a 5.63-g sample of wood's metal has been added to the water in a 10-mL graduated cylinder, the new water level is 8.7 mL. What was the water level in the cylinder before the sample was added? A chemistry student at a yard sale considers buying a silver coin. The student asks for permission to test the coin to determine whether or not it is really pure silver. She finds that the coin has a mass of 15.79 g. Submerging the coin in 12.3 mL of water, the student finds that the new water volume is 13.8 mL. Based on these data and Table 2, could the coin be silver? Briefly explain.
