5 Metric System International System of Units (SI) 12341234 Length – meter (m) Mass – gram (g) Volume – liter (L or l) Time – second (s) Temperature – Celsius (C) or Kelvin (K) Amount of substance – Mole (mol) Energy- Joule (J)

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

7 Significant Figures Rules in NB 1. Non-zero digits are always significant. 26.38= 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. 0.00500= 3 SF 0.03040= 4 SF

8 Metric and Significant Figures Homework in NB 12341234 Show your work (conversion factor). 1.1.93 m= 193 cm 2.50 cm= 0.0005 km 3.1000 g= 1 kg 4.14,576 L= 145.76 hL 5.658 dag= 6580 g How many significant figures? 6. 3.0800 5 SF 7. 0.00418 3 SF 8. 7.09 x 10 5 3 SF 9. 91,600 3 SF 10. 0.003005 4 SF 11. 3.200 x 10 9 4 SF 12. 780,000,000 2 SF 13. 0.0101 3 SF
