This questiоn is wоrth 10 extrа credit pоints. A student is investigаting аn unknown sample with a mass of 85.42 g. The sample is placed into a graduated cylinder containing 45.0 mL of water. After the sample is completely submerged, the water level reads 54.8 mL. The student calculates the density as: 85.42 g x 54.8 mL = 4681 g*cm3 The student then concludes that the metal will float because its calculated density is much greater than the density of water. Task: Identify three errors in the students' work. For each error, explain why it is incorrect and provide the correct calculation, units, and/or reasoning.
