The density of a rock will be measured by placing it into a graduated cylinder partially

Chapter 3, Problem 9

(choose chapter or problem)

The density of a rock will be measured by placing it into a graduated cylinder partially filled with water, and then measuring the volume of water displaced. The density \(D\) is given by

\(D-m /\left(V_{1}-V_{0}\right)\), where m is the mass of the rock, \(V_{0}\) is the initial volume of water, and \(V_{1}\) is the volume of water plus rock. Assume the mass of the rock is \(750 \mathrm{~g}\), with negligible uncertainty, and that \(V_{0}=500.0 \pm 0.1 \mathrm{~mL}\) and \(V_{1}=813.2 \pm 0.1 \mathrm{~mL}\). Estimate the density of the rock, and find the uncertainty in the estimate.
