This questiоn is wоrth 10 extrа credit pоints. A student is аttempting to determine the density of аn irregularly shaped metal object. The mass of the metal is measured as 85.42 grams using an analytical balance. To find the volume, the student uses a graduated cylinder partially filled with water. The initial volume of water is 45.0 mL. After carefully adding the metal sample, the water level rises to 54.8 mL. The student records the following calculation for density: Densitymetal = 85.42 g x 54.8 mL = 4681.0g/cm She concludes that because this value is much larger than the density of water (1.00 g/mL), the metal must float. Task:Identify two errors in the student’s calculation and/or reasoning. Consider errors related to the mathematical setup, the use of units, significant figures, and the interpretation of the density concept. For each error, explain why it is incorrect and provide the correction.
