Which of the following is closest to the typical density of porcelain?

• A. 1.0 g/cm^3
• B. 7.9 g/cm^3
• C. 2.6 g/cm^3
• D. 2.4 g/cm^3

Answer: (C)

Verified step by step guidance

1. Understand that density is defined as mass per unit volume, expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\) with units typically in g/cm\(^3\) for solids.
2. Recall that typical densities vary widely depending on the material: for example, water is about 1.0 g/cm\(^3\), metals like iron are around 7.9 g/cm\(^3\), and ceramics such as porcelain usually have densities between 2 and 3 g/cm\(^3\).
3. Recognize that porcelain is a type of ceramic material, which is generally less dense than metals but denser than water or many plastics.
4. Compare the given options to typical ceramic densities: 1.0 g/cm\(^3\) is too low (close to water), 7.9 g/cm\(^3\) is typical for metals like iron, and 2.4 g/cm\(^3\) and 2.6 g/cm\(^3\) are both reasonable for porcelain.
5. Select the value closest to the known typical density range for porcelain, which is around 2.5 to 2.6 g/cm\(^3\), making 2.6 g/cm\(^3\) the best choice.
