Depending on the needed concentration of salt !
yo its crazy.it defenetly need salt water to live.but you can make your own salt water at home by adding much salt
As much table salt as you can stir in the boiling water until no more salt will dissolve. You will see salt dissolve once you stir some table salt in the boiling water, hot tap water is unsufficient.
Goldfish don't need salt because they are Freshwater Fish!

It dosent matter. It dosent matter.
You need to boil it.
For each 1000ml (1 litre) you need about 35gms of salt to reach a similar saltiness to sea water. By volume, 35gms is roughly 2 tablespoons (UK).
it depends on how much salt is in the water. if there is enough, the soda can will float.
350grams
Depends how much tap water you are using. :)
