Chapter 1, Problem 106
The density of polypropylene, a plastic commonly used to make bottle caps, yogurt containers, and carpeting, is 0.55 oz/in3. Calculate the density in units of g/cm3
Verified step by step guidance1
Identify the given density of polypropylene: 0.55 oz/in^3.
Convert ounces to grams using the conversion factor: 1 oz = 28.3495 g.
Convert cubic inches to cubic centimeters using the conversion factor: 1 in^3 = 16.387 cm^3.
Set up the conversion equation: (0.55 oz/in^3) * (28.3495 g/oz) / (16.387 cm^3/in^3).
Simplify the expression to find the density in g/cm^3.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as mass per unit volume, typically expressed in units such as grams per cubic centimeter (g/cm³) or ounces per cubic inch (oz/in³). It is a physical property that helps identify substances and can be used to determine whether an object will float or sink in a fluid.

Density Concepts
Unit Conversion
Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. In this case, converting density from ounces per cubic inch to grams per cubic centimeter involves using conversion factors that relate these units, ensuring that the numerical value accurately reflects the same physical quantity.

Conversion Factors
Conversion factors are ratios that express how many of one unit are equal to another unit. For example, 1 oz is approximately 28.35 grams, and 1 in³ is approximately 16.387 cm³. Using these factors allows for accurate conversion between different measurement systems, which is essential for solving problems in chemistry.
