You can dissolve 1/4 cup of salt in one cup of water. Slightly (10%) more if the water is boiling.
you put it in a cup of water or something that has water in it
To make salt water, simply dissolve salt in water until no more salt can be dissolved. The ratio is typically about 1 cup of salt per gallon of water. Stir the mixture until the salt is completely dissolved. You now have salt water ready for use.
About 50 mils.
You can separate salt and water by evaporating the water. Heat the saltwater solution until all the water evaporates, leaving behind the salt. Alternatively, you can use a process called distillation to boil the water, collect the steam, and then condense it back into liquid water, leaving the salt behind.
Eggs can float in water because of the air pocket located at the wider end of the egg. As the egg ages, more air enters the egg through the porous shell, making it less dense and causing it to float. This phenomenon can be used to determine the freshness of an egg - the older the egg, the more it will float.

Things can float better in salt water, due to density. For a visual experience, try getting 2 cups, fill both with tap water, and put salt in one cup, then mix it in. Get 2 eggs, and put one in each cup, keep on adding salt to one cup, until the egg floats. I hope I answered your question!
No. First it dissolves; when you add too much salt it sinks to the bottom.

Well it takes 1 cup and 1 teaspoon for it to officially float on the water to be able to understand the ocean salt water and it's density.
It depends on how much salt is in the water. So if a cork sinks in regular water you should put a little bit more than a 1/4 cup.
A styrofoam cup will float in water because styrofoam is less dense than water, causing it to displace water and float.
According to the experiment it takes one half cup of salt. 1 cup of salt is equal to 48 teaspoons. So a half of cup would be 24 teaspoons of salt.
The sea has to have at least 4 tablespoons of salt in order for an egg to float.
About 50 mils.
The salt will dissolve in the water, the water will evaporate and is turned to water vapor(steam) and the salt will be the only one left behind in the cup.
