The density of light oil is 0.78 kg/L. What is the volume of 5.72 kg of this oil in units of cm3?

We can calculate for the volume using the formula:

volume = mass / density

Therefore:

volume = 5.72 kg / (0.78 kg / L)

volume = 7.33333 L

We know that 1 mL = cm^3 and that 1 L = 1000 mL, therefore: 1 L = 1000 cm^3

volume = 7.33333 L * (1000 cm^3 / L)

volume = 7,333.33 L
