Verified step by step guidance1
Understand the relationship between grams (g), kilograms (kg), and milligrams (mg). Specifically, 1 kg = 1000 g and 1 g = 1000 mg.
To convert grams to kilograms, divide the mass in grams by 1000 because kilograms are larger units: \(\text{mass in kg} = \frac{\text{mass in g}}{1000}\).
To convert grams to milligrams, multiply the mass in grams by 1000 because milligrams are smaller units: \(\text{mass in mg} = \text{mass in g} \times 1000\).
Apply these conversions to 9.31 g: calculate \(9.31 \div 1000\) to get the mass in kilograms and \(9.31 \times 1000\) to get the mass in milligrams.
Compare the converted values to the given options to identify which one matches the equivalent mass of 9.31 g.
