3. The density of a liquid is 0.785 g/mL at 25 degrees Celsius. Convert it into kg/L. Show your unit cancellation setup for the conversion. This is a harder one. Hint: 1 kg = 1000 g, 1 L = 1000 mL.

Answer 1

To solve this problem, you need to convert grams to kilograms, and milliliters to liters.

0.785 g / 1 mL x 1 kg / 1000 g x 1000 mL / 1 L = 0.785 kg/L

Yes, the answer is the same as what you started with! There are 1000 mL in 1 L, and there are 1000 g in one kg.
