How Do “Measure” Chemistry? Metric System (International System of Units) Significant Figures Scientific Notation Dimensional Analysis

Significant Figures Rules in NB 1. Non-zero digits are always significant = 4 SF 2. Any zeros between two significant digits are significant. (Captured Zeros) 406= 3 SF 91,600= 3 SF 3. A final zero or trailing zeros in the decimal portion ONLY are significant = 3 SF = 4 SF

Metric and Significant Figures Homework in NB Show your work (conversion factor) m= 193 cm 2.50 cm= km g= 1 kg 4.14,576 L= hL dag= 6580 g How many significant figures? SF SF x SF 9. 91,600 3 SF SF x SF ,000,000 2 SF SF

Significant Figures Rules in NB 1. Non-zero digits are always significant = 4 SF 2. Any zeros between two significant digits are significant. (Captured Zeros) 406= 3 SF 91,600= 3 SF 3. A final zero or trailing zeros in the decimal portion ONLY are significant = 3 SF = 4 SF
