Adding any amount of salt to water you obtain salt water; it is important to know the desired concentration.
Depending on the needed concentration of salt !
it depends on how much salt is in the water. if there is enough, the soda can will float.
Depends how much tap water you are using. :)
350grams
This depends only on your needs for the concentration.
even a bit of salt can make a (tiny) bit of electricity. the more salt, the more electricity

The amount of salt water you get will depend on the concentration of salt in the water. When you mix salt with water, the salt dissolves into the water to increase its volume slightly. The overall volume of the salt water will be the sum of the volumes of the original salt and water components.
