Explanation:

Part A (Convert to kg):

Step1: Recall g to kg conversion

$1\ \text{kg} = 10^3\ \text{g}$, so conversion factor is $\frac{1\ \text{kg}}{10^3\ \text{g}}$

Step2: Multiply value by conversion factor

$2.294 \times 10^{10}\ \text{g} \times \frac{1\ \text{kg}}{10^3\ \text{g}} = 2.294 \times 10^{7}\ \text{kg}$

Part B (Convert to Mg):

Step1: Recall g to Mg conversion

$1\ \text{Mg} = 10^6\ \text{g}$, so conversion factor is $\frac{1\ \text{Mg}}{10^6\ \text{g}}$

Step2: Multiply value by conversion factor

$2.294 \times 10^{10}\ \text{g} \times \frac{1\ \text{Mg}}{10^6\ \text{g}} = 2.294 \times 10^{4}\ \text{Mg}$

Answer:

Part A: $2.294 \times 10^{7}\ \text{kg}$
Part B: $2.294 \times 10^{4}\ \text{Mg}$
