How much does a stone weight in salt water?
Correct formulation: "How much does a stone weigh in salt water?"Answer: The same as it does in the air, water, anywhere.
What is a stone's mass in water?
The mass of a stone in water is the mass of the stone outside water. The mass of an object is always its mass. (This assumes we are not discussing the theory of relativity.) On Earth, or the Moon or in water or not, mass is mass. What might be relevant, however, is the weight of a stone in water compared to the weight of a stone outside the water. Weight and mass are different. If you hold a stone in water and hold the same stone in air, you can feel a difference in the force you must apply to support the stone. In water, the stone feels a buoyant force equal the the weight of the water displaced. That is Archimedes principle. There is a difference in the apparent weight of a stone in water and a stone out of water equal to the eight of the water displaced.
Where stone sink in water?
A stone will sink in water because its density is greater than that of water. This means that the weight of the stone is heavier than the weight of the displaced water, causing it to sink.
In the English weight system how much does a stone weigh compared to American weight system?
In the English weight system, a stone weighs 14 pounds. In the American weight system, the closest equivalent is a pound.
Why it is easierto lift a heavy stone under water than in air?
It is easier to lift a heavy stone under water because the water provides buoyant force that counters the weight of the stone. This buoyant force reduces the effective weight of the stone when submerged in water, making it easier to lift. In air, there is no buoyant force to counteract the weight of the stone, so it feels heavier to lift.

How can you calculate the volume of a stone when its in water?
you subtract the weight of the water from the weight of the measuring cylinder and you get the volume of the stone
Where stone sink in water?
A stone will sink in water because its density is greater than that of water. This means that the weight of the stone is heavier than the weight of the displaced water, causing it to sink.
How do you make a stone be the same weight in air and water?
Let us say the stone is suspended in a medium by an ideal spring, which displays the "weight" of the stone in that medium. The stone reads "w" pounds in weight in air. The same stone will read less in water (w-x); the stone, being a solid, displaces an amount of water equal to the volume of the stone, and the stone will weigh less by the weight of the water (x). So in this case, the two weights have to be different, no matter how small the stone is, unless the stone has the same density as water or the stone is hollow with no crust thicknesses and a tiny hole to let water in -- all purely hypothetical.

Why does a person lift a heavy stone immersed in water as compared to air?
If the question is asking "for what reason would a person lift a heavy stone immersed in water as opposed to air?" then the answer is buoyancy. When immersed in water there will be an upward force on the bottom of the stone due to the volume of water it has displaced. This upward force will make the stone seem lighter to the person lifting it by decreasing the amount of force they need to exert to lift it.
A stone will sink in water because a stone?
It is more dense than water, and [presumably] it is not shaped in such a way that all of its weight can be displaced before the stone submerges.
What stone do not sink in water?
A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.
This is expressed as the weight of a mineral compared with the weight of an equal volume of water?
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
Can objects of the same weight have different buoyancies?
Sure. A small stone can have the same weight as an inflated party balloon. But the balloon has more buoyancy, so it floats on water, while the stone sinks like a stone.
