Significant Figures

Think back to your brainstorm from this topic's Warm-Up. Were you correct in any of your guesses as to why significant digits are important in measurement and in chemical calculations? Significant digits convey to others how accurate a measurement is and provide an indication on the uncertainty of a measurement. As you complete your chemistry studies, make sure to follow the guidelines for significant digits. In addition, you may need to use scientific notation to communicate very large or very small numbers in a more efficient and understandable manner.
