Conversion Factors
Identify one or more correct conversion factors for the equality of gigagrams and grams.
a. \frac{1\,\mathrm{Gg}}{1\times10^{9}\,\mathrm{g}} b. \frac{1\times10^{-9}\,\mathrm{g}}{1\,\mathrm{Gg}} c. \frac{1\times10^{9}\,\mathrm{Gg}}{1\mathrm{~g}} d. \frac{1\times10^{9}\,\mathrm{g}}{1\,\mathrm{Gg}}
In Table 1.8, the equality for gigagrams and grams is 1 Gg = 1 × 10^{{9}} g.
Answers a and d are correctly written conversion factors.
