Calculate the volume of the bar and the error in the volume using your measurements with the ruler. Repeat with the measurements with the vernier caliper. Calculate two values for the density of the brass cylinder and the error in the density from mass and each of the values for the volume. It should include, in table format, the results of all your measurements of the dimensions of the brass bar with uncertainties. Use separate columns for di?erent measuring devices....

The density experiment involves taking average mass and displaced volume measurements for multiple samples of metal. A student ascertained that the identity of their unknown metal was zinc (d 7.14 g/mL). However, upon consulting their teaching assistant, they learned that the true identity of the metal was copper (d = 8.96 g/mL). What error could the student have made when performing the experiment that would have led to the student's original conclusion? 7.
