Answer:
[tex]\boxed{3.22 \times 10^{6}\text{ kg}}[/tex]
Explanation:
1. Convert gigagrams to grams
10⁹ g = 1 Gg
[tex]\text{Mass} = \text{ 3.22 Gg} \times \dfrac{10^{9}\text{ g}}{\text{1 Gg}} = 3.22 \times 10^{9}\text{ g}[/tex]
2. Convert grams to kilograms
1 kg = 10³ g
[tex]\text{Mass} = 3.22 \times 10^{9}\text{ g} \times \dfrac{\text{1 kg}}{ 10^{3}\text{ kg}} = 3.22 \times 10^{6} \text{ kg}\\\\\text{3.22 Gg =} \boxed{\mathbf{3.22 \times 10^{6}\textbf{ kg}}}[/tex]
