Significant Figures, Scientific Notation and Conversions Practice Worksheet 1. Determine the number of significant figures in the following values: a) $190.82\mathrm{mL}$ f) 8 lions b) $0.0065\mathrm{g}$ g) $5.20\times 10^{14}\mathrm{pg}$ c) $95.00\mathrm{mm}$ h) $3.07\times 10^{11}\mathrm{gal}$ d) $5300\mathrm{nm}$ i) $6.0300\times 10^5\mathrm{m}$ e) $732.010\mathrm{lb}$ j) 3215 miles 3 $\frac{3}{\frac{3}{5}}\frac{4}{4}$ 2. Round the following values to 3 significant figures: a) $3.68801-3.69$ f) $0.04219750.0422$ b) 3.68493 g) 150.7256 c) $3.68529-3.69$ h) $0.0138770.0139$ d) $17.04819217.0$ i) $4.86250\times 10^{9}4.86$ e) 8.75430 8.75 j) $4.0098\times 10^{-12}4.01$ 3. Perform the following unitless calculations and round the final answer to the proper number of significant figures. Assume that all of the numbers came from measurements. a) $3.41-0.086652=3.32$ f) $0.87+4.061+10.4=$ 15 b) $17.441÷3=$ g) $16\times 841.4÷16.300=$ c) $21.01\times 2.0=$ 42 h) $14.044+8.11+3.4=$ 83 d) $18.7644-3.472+0.4101=$ 15.70 4. Convert the following values into scientific notation, or if given in scientific notation, convert back to a regular number: a) $52,000052\times 10^3$ g) $250,000,000,000,000,000,00025\times 10^{19}$ b) $0.00066\times 10^{-4}$ h) $\mathrm{0.00000065096.509}\times 10^{-7}$ c) $789,000,000,789\times 10^6$ i) $\mathrm{0.00000095489.548}\times 10^{-7}$ d) $7.66\times 10^{-2}0.0766$ j) $7.8\times 10^{5}780,000$ e) $4.75\times 10^{-4}0.000475$ k) $6\times 10^{-3}0.006$ f) $9\times 10^{8}900,0001000$ l) $6.022\times 10^4-60220$
