There are three rules on determining how many significant figures are in a number: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant. Focus on these rules and learn them well. They will be used extensively
RULES FOR SIGNIFICANT FIGURES. 1. All non-zero numbers ARE significant. The number 33.2 has THREE significant figures because all of the digits present are non-zero. 2. Zeros between two non-zero digits ARE significant. 2051 has FOUR significant figures. The zero is between a 2 and a 5. 3. Leading zeros are NOT

Determining the Number of Significant Figures, Addition and Subtraction, Multiplication and Division, Rounding Off make the measurement allows. We can achieve this by controlling the number of digits, or significant figures, used to report the measurement. Rules for counting significant figures are summarized below.
Following are Summaries from Two Chemistry Education. Web Sites Concerning Significant Figure Rules. From dbhs.wvusd.k12.ca.us/SigFigs/SigFigRules.html. There are three rules on determining how many significant figures are in a number: 1. Non-zero digits are always significant. 2. Any zeros between two
Rule 1: Non-zero digits are always significant. Rule 2: Any zeros between two significant digits are significant. Rule 3: A final zero or trailing zeros in the decimal portion ONLY are significant.
5 Sep 2014 Zeros to the left of the first non-zero digit are not significant. If a number ends in zeros to the right of the decimal point, those zeros are significant. 2.00 (3 sig figs) {This signifies greater accuracy.} If a number ends in zeros to the left of the decimal point, those zeros may or may not be significant.
A Short Guide to Significant Figures. Quick Reference Section. Here are the basic rules for significant figures - read the full text of this guide to gain a complete understanding of what these rules really mean! How does one tell how many significant digits there are in a given number? • The leftmost digit which is not a zero is
Significant Figures. (Adapted from Prof. Pasternack, JHU Chemistry). A good tutorial on significant figures can be found at www.chem.sc.edu/faculty/morgan/resources/sigfigs/. The rules for significant figures can be summarized as follows: 1. To determine the number of significant figures: o All nonzero digits are
Scientific Notation and Significant Figures. Notes on scientific notation and significant figures prepared by Dr. Masingale, Le Moyne College Department of Chemistry. Scientific Notation. All numbers, regardless of magnitude, can be expressed in the form: N x 10n. where. N is a number, either an integer or decimal, between
