Answer:
2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.
Explanation:
The units are kg, μg, mg and metric tons (1metric ton = 1000kg)
To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:
kg:
2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg
mg:
2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg
μg:
2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg
metric tons:
2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons
