DENSITY OF REGULARLY SHAPED OBJECT
Title
I. Introduction
Different materials have different weights; one material may be lighter while others
are heavier. This is attributed to one of the characteristic properties of a material called
density. A closely packed material is denser and heavier while a loose one is less dense
and lighter.
Density is a scalar quantity and is defined as the mass per unit volume of the
material. The standard unit of density is kilogram/m3. Other units are gram/cm3 and
slug/ft3.
II. Objective:
To determine experimentally the density of regularly shaped objects.
III. Apparatus/Materials:
Ruler, platform balance, empty Pringles can, empty Yakult Bottle (80 mL), empty
Century Tuna can (180 g), empty Selecta Ice Cream Tub (1.5 L), and empty
Ginebra San Miguel Gin Bottle (350 mL)
IV. Procedure:
1. Using a balance, determine the mass of each sample.
2. On a separate sheet of paper, proceed with the actual computations of the volume
of the objects.
•
•
Draw the object and label its dimensions.
Show the formula used and the complete calculation.
•
•
For example, the Century Tuna can is cylindrical. Thus, its volume is calculated
using the formula:
Volume = π × (D/2)² × H
•
Apply the same process for other shapes (e.g., rectangular box, sphere, etc.).
3. Use the results to calculate the experimental density of each sample with the
formula:
Density (ρ) = mass ÷ volume
4. Compare the computed densities with the standard values from a reliable
reference in the internet. Then, calculate the percentage difference using the
formula:
Percentage Difference = (Standard Value – Experimental Value) ÷ Standard
Value × 100%
5. Repeat procedures 1 to 4 for the remaining samples.

VI. Answer the question (you may use the back pages if needed).
1. State the possible sources of error resulting to the percentage difference in the mass
densities of the materials and give suggestions on how these errors can be minimized.
