It depends on the depth of the water - whether it is spread over a huge area or concentrated over a small area.
When you stand on a floor, the force that you exert on the floor because of your weight is equal to the force with which the floor supports your weight.
a force of depend on mass
How much force you can exert at one time.
The force would be the weight of the object.
As much as is available. That of course does not mean the paper can withstand it.
In orbit your weight is zero.
The floor is a stationary object (in relationship to you). The floor will provide only enough force to match the force of gravity holding you down. It has to be equal.
It is roughly the same as the weight of a gallon of water, because the bouyancy force is equal to the weight of water displaced (the weight of the air being negligible). A UK gallon of water weighs almost exactly 10 pounds, while a US gallon weighs about 8.35 pounds.
Not that much actually.
Your mass is how much matter you are made up of. Your weight is how much force you exert on your surroundings. If the force of gravity is greater or weaker, then your constant mass will exert more, or less force on the surroundings, ie, your weight will be different.
the answer is a mega gallon of water
