Answer:
The answer is: 0.8 Liters
Step-by-step explanation:
In order to find the volume of the oil, we have to divide the weight of the oil over the density, so we are going to know the volume in mL:
(640 g) / (0.8 g/ml) = 800 mL
Now, if we want the answer in liters, and we know 1 L (liter) is 1000 mL (mililiters), just divide 800 mL over 1000.
