Solved Examples on Calculation of Density
Example 1. Calculate the density of water if it has a mass of 1160kg and a volume of 1m3?
Solution:
Given,
Mass = 1160kg
Volume = 1m3
Density is given by the formula:
Density = Mass / Volume
ρ = 1160/1 = 1600 kg/m3
Example 2. A block of wood has a mass of 1200 grams and a volume of 600 cubic centimeters. Calculate the density of the wood block in grams per cubic centimeter.
Solution:
Given,
Mass = 11200 grams
Volume = 600 cubic centimeters
Formula: Mass/Volume
Substitute the given values into the formula
Density = 1200 grams/ 600 cubic centimeters
Density = 2 grams/ cubic centimeter
The density of the wood block is 2 grams per cubic centimeter.
Example 3. A liquid has a density of 0.8g/mL and a volume of 100 mL. Calculate the mass of the liquid in grams.
Solution:
Given,
Density = 0.8g/mL
Volume = 100mL
The formula for calculating mass using density and volume is:
Mass = Density × Volume
Substitute the given values into the formula:
Mass = 0.8g/mL × 100mL
Mass = 80 grams
The mass of the liquid is 80 grams.
How to Find Density
Density represents the mass of a substance per unit volume. Methods to find density are an important component of physics and chemistry. It plays an important role in scientific research, technical design, material characterization, and quality control methods. The ability to accurately identify density is essential for understanding physical properties, identifying objects, and making informed decisions in a variety of industries. In this article, we will explore various methods of measuring density, and the principles, methods, and application of density.
