Significant Figures (Sig-Figs)
- An estimated digit is considered a significant figure.
- The estimated digit can be found as the last significant figure.
- Counting values, like the number of people, are not treated as significant figures.
- Constant conversion factors do not count as significant figures.
- All non-zero numbers are significant figures.
- Examples of significant figures:
- The number 305 has 3 significant figures.
- The number 3555.00 has 6 significant figures.
- The number 0.0355 contains 3 significant figures.
- The number 0.0200 possesses 3 significant figures.
- The number 3500 has 2 significant figures.
- The scientific notation 3.500 x 10^3 has 4 significant figures.
Mathematical Operations and Significant Figures
- In addition or subtraction, the correct number of significant figures comes from the number with the fewest decimal places.
- In multiplication or division, the total significant figures are determined by the number with the fewest significant figures.
- For conversions, the correct number of significant figures derives from the initial value.
Scientific Notation
- 560,000 in scientific notation is written as 5.6 x 10^5.
- 8.34 x 10^-2 can be rewritten as 0.0834.
Measurement Concepts
- Accuracy refers to how close a measurement is to the actual true value.
- Precision measures how closely grouped multiple measurements are to each other.
Density
- Density is defined as mass divided by volume (m/v).
- The density of water is established at 1 g/mL.
