Significant Figures and Rounding - 8/26/08 1 Worksheet: Significant Figures Each measurement has its own precision leading to values with different numbers of significant figures. Calculations often involve numbers from different measurements and the final answer must take differences in precision into account. Often, the final answer must be rounded to account for uncertainty arising from the calculation. This worksheet will give you a chance to practice identifying which digits are significant, rounding answers to the correct number of significant figures, and performing different calculations. A. Identifying Significant Figures Rules for determining significant figures: 1. All non-zero digits are significant. 2. Zeros to the right of a non-zero number but to the left of an assumed decimal point may or may not be significant. In this class, assume they are not unless told otherwise. 3. All zeros between two non-zero digits are significant. 4. All zeros to the right of a decimal point are significant. 5. All zeros to the right of a non-zero digit but before a decimal place are significant. 6. All zeros to the left of a non-zero digit are not significant. 7. All zeros to the left of a decimal place are not significant unless there is a non- zero digit to their left. Assume that the following numbers are measurements. Place an asterisk above each significant figure. a) 6.700 b) 50,503 c) 0.0087 d) .01 e) 0.01 f) .0050 g) 340 h) 2,000. i) 10.05 j) 265,200 k) 2.00 x 10 6 l) 5,002.9
