🧪 Chemistry by Chang – Problem 1.21 | Significant Figures | Steemit Science
Hello Steemit learners! 👋🔬
Here’s another key exercise from Raymond Chang’s Chemistry (14th Edition), in Chapter 1: Measurement and the Properties of Matter. This problem focuses on identifying the number of significant figures in various measurements — a fundamental concept in chemistry and all experimental sciences.
🔹 Problem 1.21:
Significant figures tell us about the precision of a measurement, not just its value. Understanding how to count them correctly is crucial for reporting experimental data properly.
