Hexane, isolated from other gasoline components, serves as a solvent for vegetable oils, such as peanut oil and soybean oil. The gas solubility Rs is defined as the number of standard cubic feet of gas which will dissolve in one stock-tank barrel of crude oil at certain pressure and temperature. The solubility of a natural gas in a crude oil is a strong function of the pressure, temperature, API gravity, and gas gravity. bond and therefore is not as attracted to the water molecule. 3. Explain why oil dissolves easily in gasoline but not in water. 3 marks 4. Assume you’ve just changed your car’s tires and your hands are covered in greasy dirt.
