You are asked to determine the mass of a piece of copper using its reported density 8.96g/mL, and a 150-mL graduated cylinder. First, you add 105mL of water to the graduate cylinder, then you place the piece of copper in the cylinder and record a volume of 137mL. Which of the following is the correct mass of the copper reported with the correct number of significant figures?
A. 3.5x10^-3 g
B. 287g
C. 2.9x10² g
D. 3.48x10^-3 g
E. 286.72g

A piece of metal ore has a density of 5.15 g/cm3. When a student places an 11.5g sample into a graduated cylinder containing 15.0 mL of water. What will be the final reading of the water volume on the graduated cylinder once the ore is placed in the water? Your answer must have the correct number of significant figures?

You weight a piece of metal to determine that it has a mass of 16g. You then place this same piece of metal in a graduated cylinder containing 21 mL of water. After the addition of the metal to the graduated cylinder, the water level rises to 28mL. What is the density of the metal?

Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...
