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, the mass of the sealed cup of water would remain the same as long as no water is added or removed from the cup. The mass is a measure of the amount of matter in the system, which would not change in a sealed environment.
The answer will depend on the size of the cup and, therefore, the quantity of water in it!
It remains 200 mg. Placing it anywhere does not change its mass

A cup of water and a cup of ice would have the same volume and mass because they fill the cup to the same level. However, the cup of ice would have a lower density than the cup of water because ice is less dense than liquid water due to its expanded crystal structure.
A standard cup is 226 grams of water
There is no carbon in a pure cup of water.
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.
