Significant Figures

In this assignment you will: Explore the determination of significant figures in measurements through several resources. Write an essay in which you describe how the number of significant figures are determined, what they represent, and how they are used. Follow the links to the web sites found in the "Source Material" section and use your textbook ("Chemistry: The Molecular Nature of Matter and Change", by Martin S. Silberberg) to gather information about handling significant figures. Write a comprehensive, coherent essay concerning the nature of significant figures, how they are recognized, how the are assessed after performing a calculation involving measured data, and how numbers are rounded to the proper number of significant figures. The "Guiding Questions" below are intended to help you to determine what concepts should be included in your essay, but do not simply write a list of answers to those questions - write an informative essay on the subject of significant figures. In a numerical value, how do you know which digits are significant and which are not? When performing a measurement, how you you know how many significant digits to record? Comment on the nature of the last significant digit in any measured value. When you are given a numerical value that is the result of a measurement, what do the number of significant digits tell you about the precision of the measurement? About its accuracy? What rules are followed in determining the number of significant digits in the answer to a calculation involving measured values? What is an "exact" number? How does it affect calculations? In a multi-step calculation, how should significant figures be handled? How does the course policy on significant figures differ from that of the textbook? How should you round an numerical result so that it contains the proper number of significant digits?
