An antique solid brass spherical pendulum bob from a grandfather clock is stamped with 500 g500\text{ g}500 g. A conservator places this bob on a calibrated digital scale, which displays a reading of 489.2 g489.2\text{ g}489.2 g.
The conservator concludes: "The digital scale is malfunctioning and cannot be trusted." Evaluate this conclusion.
The conservator wishes to determine the density of this brass bob to confirm its material composition. They already have an accurate value for its mass. Describe the remaining experimental procedure, precautions, and calculations they must perform to find the density.
