This depends on the concentration of salt in water; this is your choice.
5 grams of salt in 10 grams of water is more concentrated (50%) compared to 18 grams of salt in 90 grams of water (20%).
5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%

20% salt solution is the equivalent of adding 200gr salt in a 800 ml (1000ml -200ml) of water. you now have one liter of a 20% solution.
After 50 grams of water evaporate, you will be left with 50 grams of water in which the 3.0 grams of salt is dissolved. So, your solution will now contain 3.0 grams of salt dissolved in 50 grams of water.
- Sugar is not salt.- The unit of 20 is ?
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
80 parts per thousand (ppt) means there is 80 grams (g) of NaCl (salt) per 1000 grams of water. 1L is approximately 1000 grams of water; it can vary slightly depending on the temperature.
The amount of salt that can dissolve in 20mL of water depends on the solubility of the salt at that temperature. For common table salt (sodium chloride), approximately 36 grams can dissolve in 20mL of water at room temperature.
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."
The resulting mass of the mixture is 35 grams (5 grams of salt + 30 grams of water).
To find the percent of salt by weight in the water, you need to calculate the total weight of the salt in the water. Since the salt content is 51.3 grams per liter and you have 1 liter of water, the weight of salt in the water is 51.3 grams. To find the percentage, divide the weight of the salt by the total weight of the solution (1000 grams for 1 liter of water) and multiply by 100. Therefore, the percent of salt by weight in this example would be 5.13%.
