1. Determine the number of significant figures in each of the following:
- __________ 75.02mm
- ___________ 0.0049 g
- __________ 18.90 mL
- ___________ 150 cm
- __________ 12 test tubes
- ___________ 150. Cm
2. Rewrite the quantity 827,000,000,000,000 picoseconds to show:
- 1 sig. fig. ________________________________
- 2 sig. figs. _________________________________
- 3 sig. figs. _________________________________
- 4 sig. figs. ________________________________
- 5 sig. figs. ________________________________
3. Rewrite the quantity 0.0031904 kg to show:
- 1 sig. fig. _______________________________
- 2 sig. figs. _______________________________
- 3 sig. figs. _______________________________
4. Round each of the following to 3 significant figures:
- 16.8477 L __________
- 5.6732 __________
- 0.14986 L __________
- 861.85 __________
- 4.203 x 104 km _________
- 5.0981 x 10‐3 __________
- 0.00318756 m __________
- 0.09025011 __________
5. Perform the following calculations and report the results with the correct number of significant figure and proper units.
- \(0.0677 + 48.1 + 82.7655\)
- \(43.8316 ‐ 29.5706\)
- \(\dfrac{8506}{6.524} \times 0.02 \)
- \(0.0222 \times 0.7000 \times 8.702\)
