There is really no way to answer the question definitively. It can only be answered in general, theoretical terms. Since you didn't mention the VOLUME of the object, we cannot determine the amount of salt water it displaced. The object's weight would be reduced by an amount equal to the weight of the water displaced. Further, since we don't know the density of the salt water -- salt water is denser than fresh water, and its density varies with salinity -- that further confounds the problem. First, Pascal's principle tells us that fluid pressure on a submerged object is exerted in all directions. But since fluid pressure increases with depth, the pressure on the bottom of the object is greater than on the top, so a net upward force -- buoyancy -- is created. Second, objects of equal volume will have the same buoyancy. (That is somewhat counter-intuitive, since many people assume that a rock will be less buoyant than, say, a similarly sized piece of cork.) The buoyant force opposes the object's weight, so submerged objects have lower effective weight than objects in air. If the buoyant force is greater than an object's real weight, it will rise; if not, it sinks. Third, since buoyancy is proportional to the volume of the submerged object, if the object compresses significantly as it reaches greater depth, its buoyancy will decrease and its effective or apparent weight will increase, which will cause it to sink farther.
Archimedes Principle. Archimedes said, "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." Therefore, since salt water is denser, and therefore heavier than an equal amount of water, you will be pushed upward by more force, and thus will weigh less.
Just about anything will float in saltwater, if there is enough salt in the water. The salt content of the Dead Sea is about 31%, and it's very easy for a person to float in. This is because the salt makes the water more dense, and this affects the property known as buoyancy. If the weight of an object is less than the weight of the fluid the object would displace if it were fully submerged, then the object has an average density less than the fluid and has a buoyancy greater than its weight. Make the water denser (heavier) by adding salt, and you increase the likelihood that an object will weigh less than the water it displaces, and will therefore float. http://en.wikipedia.org/wiki/Buoyancy#De…
Objects float better in salt water because the denser the water the easier the object will float for instance if your at a salt water beach you will float easier in a salt water beach then you will floating in a swimming pool.
To find the percent of salt by weight in the water, you need to calculate the total weight of the salt in the water. Since the salt content is 51.3 grams per liter and you have 1 liter of water, the weight of salt in the water is 51.3 grams. To find the percentage, divide the weight of the salt by the total weight of the solution (1000 grams for 1 liter of water) and multiply by 100. Therefore, the percent of salt by weight in this example would be 5.13%.
In short. Select an object that would just sink in water. Then using identical sized containers pour an equal amount of water into each, say 3/4 full. Then in each dissolve an increasing amount of salt, from no salt in the first, to large amounts of salt in the last. Then place the same object into each container, starting with the "no added salt" water to demonstrate it would sink in this. Then into the increasing concentrations of salt. If it is suspended in the salt solution and not the first "no added salt" water, you're proven salt water helps objects float
The amount of salt required for an object to float depends on the object's density. For example, in water, objects will float when they displace an amount of water equal to their weight. Adding salt to increase the water's density can make it easier for less dense objects to float. The specific amount of salt will vary depending on the object's weight and size.
They can float without salt - It's the ratio of water displaced by the object in relation to its weight of the object that allows it to float - not the salt content of the water.

yes An object, like a boat for example, will sink into the water until the weight of the water it displaces equals the gross weight of the object. Since salt water is denser than fresh water, a boat will sit slightly higher in salt water. (That's why the Mythbusters needed far fewer ping pong balls to raise a boat from the bottom of the bay than they originally calculated; they based their calculation on the fresh water boyancy of the ping pong balls.)
Because according to the principle of Archimedes: "Any body immersed in a liquid undergoes a bottom-up thrust equal to the weight of liquid displaced" When submerged, the boat displaces water. Since salt water has greater weight per unit volume (density) than fresh water, the weight of the displaced salt water is higher. So the ship receives a bigger push in salt water than in fresh water. So it floats more.
A grain of salt.
the salt water is denser because of the salt
what is the weight of salt water of one cubic meter
because salt has weight
Things float in water if they are less dense than the water they are floating in. Putting salt in the water makes it more dense, so things that are a little more dense than ordinary water float in salt water.
an object will float on salt water best
