This depends on the volume and concentration of this 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.
The more concentrated solution is the one containing 18 grams of salt and 90 grams of water. This is because the concentration of the solute (salt) is higher in this solution compared to the solution containing 5 grams of salt and 10 grams of water.
The volume reach the half.
If all the water evaporated, what was left in the dish would be the solutes that were dissolved in the water, such as salts or sugars. These solutes do not evaporate with the water and remain behind in the dish once the water has all evaporated.
Rock salt is separated industrially through a process called solution mining or cavern mining. This involves injecting water into underground salt deposits to dissolve the salt and then pumping the saltwater solution to the surface. The solution is then evaporated to recover the rock salt.

Heating the solution water is evaporated and crystalline dried sodium chloride remain.
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.
When a sodium chloride and distilled water solution is evaporated, the water evaporates, leaving behind solid sodium chloride crystals. The crystals are the original salt that was dissolved in the water.
The water is evaporated and the concentration of the solution become greater.
The more concentrated solution is the one containing 18 grams of salt and 90 grams of water. This is because the concentration of the solute (salt) is higher in this solution compared to the solution containing 5 grams of salt and 10 grams of water.
The volume reach the half.
During the boiling water is evaporated.
The water is partially or totally evaporated, depending on the solution concentration.

The mass of the solution would be the sum of the mass of the sodium chloride and the mass of water. So, the mass of the solution would be 17.8 grams (NaCl) + 217 grams (water) = 234.8 grams.
Once the water is evaporated away, the salt crystals are left behind.
