Disregarding the weight of the balloon or pontoon that holds the air . . .
1 cubic foot (1,728 cubic inches, 7.481 gallons) for each 62.4 pounds of weight.
Note: If the weight is hanging in the water, underthe air, then the weight itself produces some
buoyancy, and less air is required to keep it from sinking to the bottom. The amount of buoyancy
depends on the volume of the weighty object, which can't be determined from the information
given in the question. (i.e., none)
The amount of water needed to float a ship depends on factors such as the weight and size of the ship, as well as the density of the water. A ship displaces an amount of water equal to its weight, so it will float as long as it displaces its weight in water.
A 1000-gallon tank can float if it displaces a weight equal to or greater than its own weight. The weight it can float depends on the density of the liquid it's floating in. For example, in water, the tank would float if it displaces 1000 gallons of water (which weighs about 8,345 pounds).
The weight of one liter depends on the substance being measured. The weight of water is approximately 1 kilogram or 2.2 pounds, which means one liter of water weighs 1 kilogram.
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.
The displaced water should also weigh 450 N.

The weight of one liter depends on the substance being measured. The weight of water is approximately 1 kilogram or 2.2 pounds, which means one liter of water weighs 1 kilogram.
A liter is a unit of volume not weight, therefore to determine how much a liter weighs it depends on what you're measuring. A liter of water has a different weight than a liter of sand and so on.
1 liter of distilled water have exactly 1kg of mass.
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.
As much as you can! The more the better
The displaced water should also weigh 450 N.
The weight of one liter of water is approximately 1 kilogram, which is equal to 1000 grams. Keep in mind that the weight of a liter of a substance can vary depending on its density.
To determine if an object will sink or float in water, you compare the density of the object to the density of water. If the object is denser than water, it will sink. If the object is less dense than water, it will float. The principle of buoyancy, which states that an object will float if it displaces an amount of water equal to its weight, also plays a role in determining whether something will sink or float.
