Explanation:

Step1: Convert g to mg (Part C)

Use conversion factor $1\ \text{g}=10^3\ \text{mg}$:
$2.294 \times 10^{10}\ \text{g} \times 10^3\ \text{mg/g} = 2.294 \times 10^{13}\ \text{mg}$

Step2: Convert g to kg first (Part D)

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

Step3: Convert kg to metric tons (Part D)

Use conversion factor $1\ \text{metric ton}=10^3\ \text{kg}$:
$2.294 \times 10^{7}\ \text{kg} \times \frac{1\ \text{metric ton}}{10^3\ \text{kg}} = 2.294 \times 10^{4}\ \text{metric tons}$

Answer:

Part C: $2.294 \times 10^{13}\ \text{mg}$
Part D: $2.294 \times 10^{4}\ \text{metric tons}$
