Question

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 344-g rock that displaces 216 cm3 of water

Answer 1

density d = 1.59 g/cm^3

The density of the rock is 1.59 g/cm^3

Step-by-step explanation:

The density of an object can be derived by measuring its mass and then measuring its volume by submerging it in a graduated cylinder.

Density = mass/volume of water displaced

d = m/v ........1

Given;

mass m = 344 g

Volume of water displaced v = 216 cm^3

from equation 1, we can calculate the value of the density;

Substituting the given values;

d = 344/216 g/cm^3

d = 1.592592592592 g/cm^3

d = 1.59 g/cm^3

The density of the rock is 1.59 g/cm^3
