IP: x.x.171.138 Nicole, Let me explain another way to found the figures you want.
Using density can help you to solve the problem, as you mentioned density is 0.972 (gr/mL) or (Kg/cubic meter). 28 MT (Metric Tonnes) is not volume this mass and 28 MT is equivalent to 28.000.000 gr.
Then, 28.000.000 gr divided by 0.972 gr/mL is equal to 28.806.584,36
mL, which equal to 28.806,58 liters or 7609,91820 gallons. (1 gallon is 3.7854 liters).
As you mentioned, your source pays 500 $/MT or which is the same (500 $/MT * 28 MT) 14.000 dollars.
Finally you should divide 14.000 dollar by 7609,91820 gallons this is equal to 1.8397 $/gallon or 0.4860 $/liter.
