Because the formula for density=Mass/Volume, so since density of water is always constant, when the volume (the amount of water) increases, then the mass (in grams) will also increase to make sure the density # is the same. Mass and Volume are directly proportional. when one goes up, the other goes up, and vice versa.

∙ 15y agothe mass changes because you have two different substances together and they each have their own densities therefore they each have their own mass
Wiki User
∙ 14y agoWhen you add any two things together the resultant weight is the total of the two masses.
Wiki User
∙ 11y agoBecause you add salt in it, adding mass, but salt is soluble and dissolves in water, not changing the volume.
Wiki User
∙ 7y agoThe water increases in density, and the mass increases too.
Wiki User
∙ 7y agoThe mass of water in the solution does not change.

Why does salinity cause a decrease in dissolved oxygen?
When an ionic salt like NaCl is added to water, the ions from the salt introduced will attract the water molecules in an effort to "solvate" the ions. This has the tendency to decrease the weak affinity of non-polar oxygen molecules to water and drive the dissolved oxygen out of the polar water. In general, the solubility of a gas in a solvent is affected significantly by the presence of other solutes in the solution.
Is salt water a mixture?
well since it is salt and water i guess it is a mixture
What type of change occurs when water is added to a salt-sulphur mixture?
The salt dissolves in the water and the sand does not.
Why when the mass of the salt water is not the same amount as the water add salt?
Yes, always for all mixtures.Interestingly, the volume of the solution may not equal the volume of the two things before being mixed -- even for mixing two liquids.
How does the amount of salt in water affect the density?
General Answer:An increase in salinity causes a increase in density and conversely, a decrease in salinity causes a decrease in density. The effect is quite linear, though it has a temperature dependence that affects how much the density changes.Specific Answer:Density = M/V, so density of a substance increases if the mass increases or the volume decreases or, if both change, density increases if the mass increases faster than the volume decreases.The average density of water at the ocean's surface is about 1.025 g/ml or 2.5 % greater than pure water. This is due to the mass of added sea salts which is 3.5% or .035 g/ml. The added sea salts have a small effect on the volume, so the resulting combination is more dense than pure water.Salt has 2.165 grams per milliliter and water is 1 gram per milliliter, so if you just added one milliliter of salt and that displaced one milliliter of water, the change in mass would be 1.165 grams. Alas, that is not even close. Adding one milliliter of sodium chloride to a liter of water will only increase the volume by about one half of a milliliter.Beyond that sodium has an atomic mass of about 23 and chlorine about 35.5, while a water molecule's mass is about 18. So the components of salt are heavier than the components of water.If one takes all the factors into account, one is eventually led to the conclusion that adding salt to water does not take up the volume expected and does not increase the density exactly how you might expect and there must be some rearrangement of the molecules of water that affects how closely they fit together. This is, in fact, true and has been the subject of much study and there is much more known about this.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
Which salt will result in a temperature decrease when added to water?
KBr
What is the effect on salt on mass of a potato?
A potato will decrease in mass if salt (sodium chloride) is applied to it. The salt will absorb water which is contained in the potato.
What is the difference in weight between a gallon of salt water and a gallon of fresh water?
salt water has more mass because of the added salt so salt is heavier :)
What physical process makes salt decrease in salt water?
Adding more water will decrease the salt concentration.
Why does the density of water increase when salt is added to it?
Density = Mass/Volume As salt(mass) increases and the volume remains the same, density also increases.
Does your urine have salt?
i think salt causes the body to decrease urine.
Will the melting point of ice increase or decrease when salt is added on it?
The melting point of ice decreases when salt is added.
Why does salt water help you float?
Floating is the another name for the force called buoyancy and buoyancy is reliant on the density of the floater and the liquid the floater is floating in. The less dense the floater is, the more buoyant the floater will be. Salt, when added to water, makes the water more dense than the water by itself. This can be seen in an obvious way by filling a glass of water to the top and adding salt to it. It won't overflow as long as the salt is added in a form that dissolves rapidly. The volume doesn't increase, but the salt's mass is now added to the water's mass resulting in more mass for a similar volume. the formula for density is mass/volume. But that's not the whole story. The volume of water actually decreases when salt is added, so the effect on the density of the water is increased. Salt is an electrolyte. When dissolved the sodium and chlorine ions freely associate with the water. The presence of the ions causes an effect called electrostiction, which results in the water's molecular structure changing to a more compact form (bending if you will), which causes the volume to decrease. Since the density (mass/volume) of the human body (being over 60% water) is very close to the density of water, people may or may not float in water. Adding salt to the water increases the density of the water, not only through the added mass, but also by pulling the water molecules closer together. The increased density of the salt water will result in the increased buoyancy of the floater.
Does evaporation of salt water density to increase or decrease?
It causes the density to increase because the more salt added to water, the more buoyant or dense it becomes. Salt itself does not evaporate as the water does so as the water evaporates the salt content is effectively increased, therefore making the water more saline or dense.
Will turgidity carrot cells in salt water increase or decrease?
Turgidity will decrease in salt water because water in the carrot will flow out in order to try to equalize the high concentration of salt.
Is salt in glass?
Salt is sometimes added to glass to decrease the number of air bubbles in the mixture.
