A corn oil. Because oil is treated with a solvent. After that it is refined which gets rid of free fatty acids. Finally, it is sent through steam distillation to get rid of volatile organic compounds.
To determine the amount of water to be added, we use the equation:
M1V1 = M2V2
where M1 and M2 are the concentrations and V1 and V2 are volumes. We calculate as follows:
2.00 (125) = 0.4(V2)
V2 = 625 mL
Water to be added = 625 - 125 = 500 mL of water
Hope this answers the question.
For you to open your textbook and have the ability to read about it.
Answer:
The pH of pure water (H20) is 7 at 25oC, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2. Because of the association of pH with atmospheric gasses and temperature, it is strongly recommended that the water be tested as soon as possible.
