The mass is extremely similar. Also note, different brands of whiskey would also have slightly different mass.
No, oil has less mass.
Oil is less dense than water. Therefore, equal volumes of water and oil will not have the same mass. You can prove this by weighing each. The cup of oil will weigh less.
Since oil will float on top of water, we can assume that the weight (or mass) of water is greater than that of oil.

Yes, because water is heavier than oil.
Vegetable oil floats on water because it is less dense than water. Density is the mass of a substance divided by its volume. Since the mass of vegetable oil is less than the same volume of water, it displaces less water and floats on top.
Oil
Just melt your shortening until you have one cup. Let it cool before using. It's the same thing.
because water has oxygen in it and oil does not have oxygen in it
No cooking oil and water is NOT a solution it is a mixture. When you put cooking oil and water in the same bowl or cup in less than a minute the two will separate into two layers of liquids.
Sand is at the bottom; water above and above water the oil.
1 US cup = 236.588237 milliliters
Quite a bit, or not much, depending on the substances and on how long you are willing to wait. If you pour oil and water together, you would have a rapid separation of the oil and water, with the oil on top. If you place a sheet of lead on top of a sheet of aluminum foil, the aluminum might end up on top, but not before lunch.
