15 - 16 gram of salt
20ml of salt? ml is not the right magnitude here if it is mg than it is not concentrated
Every 100 grams (100 millilitres) of boiling water (even hard water) will dissolve a maximum of about 40 grams of salt, so anything in excess of that amount just will not dissolve. If your poured a teaspoon of salt grains into a pan of boiling water it would dissolve immediately - almost no time at all.
around 400 grams
Dissolve common salt in water. Aprroximately 6 grams in 100 mL of water,
2 grams is 2,000mg
Approx. 7,2 g at 20 0C.
This well known formula should lead you on your path: Density (grams/ml) = mass/volume

Suppose you get enough water to dissolve 10 grams in 15 minutes (I assume you're talking about dissolving in water). Then you can dissolve another 10 grams by fetching an equal volume of water and doing the same, also in 15 minutes. Keep doing this. You'll never run out of water. So I suppose the answer is "as many grams of salt as you can find". Or, reading the question differently, the answer could be "as many grams of salt you can find in 15 minutes."

probably a supersaturated solution if you heat it to dissolve all of the salt
Natrium is the latin name for sodium. Natrium chloride is salt. Measure 3 grams of salt, dissolve into 97 grams of water.
