Chapter 11: Q4PE (page 396)

A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a $240 g$ rock that displaces ${89.0 cm}^{3}$ of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes鈥� principle.)

Short Answer

Expert verified

The density of the rock is obtained as: ${2.70 g/cm}^{3}$ .

Step by step solution

Conceptual Introduction

Fluid statics, often known as hydrostatics, is a branch of fluid mechanics that investigates the state of balance of a floating and submerged body, as well as the pressure in a fluid, or imposed by a fluid, on an immersed body.

Given Data

The mass of rock is $m = 240 g$ .

The volume of the rock is $蚁 = {89 cm}^{3}$ .

Calculating the volume of the given substance

As we known that the density is the rate of mass per volume let鈥檚 put the given data in the formula given below.

$蚁 = \frac{m}{V} = \frac{240 g}{89 {cm}^{3}} = 2.7 {g/cm}^{3}$

Therefore, the density of the rock is: ${2.70 g/cm}^{3}$ .
