The salt-water mixture will have the same weight as the sum of the weights of the water and the salt. The water, itself, doesn't gain weight in a strict sense, but the salt-water mixture will be heavier than the plain water. Salt water is denser than fresh water.
Yes, the weight of any salts dissolved in water will be additive with the water.

weight of salt + weight of water = weight of salt and water in solution

Adding salt to water increases its density, causing the volume of the water to decrease slightly. This is because the salt molecules displace some of the water molecules, effectively reducing the amount of space the water occupies.

Adding salt to water will increase the volume based on the amount of salt added. This is because the saltcrystals displace the water molecules. Remember that volume is a measurement of how much space matter consumes.

Yes it does indeed change. Salt has a higher density than water does, it dissolves into the water, creating "Salt Water" The binding of salt and water increases it mass, and it takes up volume.

If you put 4 milliliters of salt into 50 milliliters of water why does the volume not increase by the amount you put in?

When you dissolve salt in water, the salt molecules spread out and fill the spaces between the water molecules, resulting in a slight decrease in the total volume due to the attractions between the water and salt particles. This phenomenon is known as partial volume contraction.


How does adding salt to water effect evaporation?

Adding salt to water increases the boiling point of water, which in turn can decrease the rate of evaporation. However, once the water is in the liquid state, the presence of salt does not significantly affect the process of evaporation.


How does adding salt to water affect the temperature?

Adding salt to water lowers its freezing point and raises its boiling point. This means that saltwater will have a lower freezing point and a higher boiling point than pure water.


How can you make salt water denser?

Density is the mass per unit volume. Therefore, adding salt increases the mass of the water by a larger scale than it does the volume of the water. Actually when you add salt to the same volume of water the mas of the water has a noticeable increase, where as the volume appears to the same ( the volume does increase; however the change is so small that it is unnoticeable ,thus we say it stays the same). So a larger mass divided by the same volume gives you an increase in density.


How does dissolving salt in water affect the mass of salt and water?

Dissolving salt in water does not change the total mass of the salt and water. The mass of the combined system will be the sum of the mass of the salt and the mass of the water. However, the volume of the solution will increase due to the added salt.

Does salt affect steam temperature?

No, salt does not affect the temperature of steam. Adding salt to water increases the boiling point of the water, but once the water has turned into steam, the temperature of the steam remains the same.


How does adding salt to water affect its freezing degree and why?

Adding salt to water depresses its freezing point. Water freezes at 0 oC but adding salt to it will make the intermolecular water to water bonds more difficult to form. The salt disrupts the structure of the solid water. Therefore, water freezes at a lower temperature if it has impurities added.
