Express each of the following in kilograms
a) `5.84 xx 10^(-3)`mg
b) `58.34`g
c) `0.584`g
d) `5.873 xx 10^(-21)`g

Explanation

To express each of the following quantities in kilograms, we will use the conversion factors for milligrams and grams to kilograms.

1. **Convert milligrams to kilograms**:
- We know that \(1 \text{ mg} = 10^{-6} \text{ kg}\).
- Therefore, to convert \(5.84 \times 10^{-3} \text{ mg}\) to kg:
\[ 5.84 \times 10^{-3} \text{ mg} = 5.84 \times 10^{-3} \times 10^{-6} \text{ kg} = 5.84 \times 10^{-9} \text{ kg} \]
