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

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the answer is c i believe
