🧱 Chemistry by Chang – Problem 1.39 | Unit Conversion: Density of Aluminum | Steemit Science
Hello Steemit science lovers! 👋⚗️
This problem comes from Raymond Chang’s Chemistry (14th Edition), in Chapter 1: Measurement and the Properties of Matter.
It focuses on one of the most common and useful conversions in materials science — expressing density in different unit systems.
🔹 Problem 1.39:
Aluminum is a lightweight metal (density = 2.70 g/cm³) used in:
- Aircraft construction ✈️
- High-voltage transmission lines ⚡
- Beverage cans 🥫
- Foils and packaging materials 📦
Question:
What is its density in kg/m³?
This conversion links the centimeter-gram-second (CGS) system to the SI (International System) of units.
It’s a great example of how dimensional analysis allows scientists to easily compare and use data across different disciplines and scales.

Aluminum’s strength-to-weight ratio is what makes it so valuable in modern engineering! ⚙️
