    Hint : \(1 mg = 10^{-3}g\) \(1mL = 10^{-3}L\)

    it might be easier to use 1000 mg = 1 g 1000 mL = 1 L that's just my opinion though

    This is one way to set up \[\Large \frac{570 \text{ mg}}{1 \text{ mL}} \times \frac{1000 \text{ mL}}{1 \text{ L}} \times \frac{1 \text{ g}}{1000 \text{ mg}} \]

    1000 mg = 1 g 1000 mL = 1 L 1000 g = 1 kg \[\Large \frac{570 \text{ mg}}{1 \text{ mL}} \times \frac{1000 \text{ mL}}{1 \text{ L}} \times \frac{1 \text{ g}}{1000 \text{ mg}} \times \frac{1 \text{ kg}}{1000 \text{ g}} \]
