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.
HOW TO SOLVE DENSITY OF GRAPHITE?
Mass = Density x Volume Density = Mass ÷ Volume Volume = Mass ÷ Density
How can a small object be densest if it doesn't have the most mass?
Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.
If you know the density and volume of a substance how could you find its mass?
density is mass divided by /volume so mass is density times volume
How do you work out the mass of an object with the density and the volume?
Density = (Mass) divided by (Volume) If you know the density and volume, then Mass = (Density) times (Volume)
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.
What is the density of rock salt?
I do not know but you can divide mass by volume and get the density. --------------------------------------------- The density of a pure salt crystal is 2,165 g/cm3. This is a true density. The density of fine powdered salt (apparent density) is variable: approx. 1 g/cm3.
How does dissolving salt in water change the density of the water?
The density increases as the mass of the solution increases but its volume remains the same.
What is the mass of 20ml of salt?
This well known formula should lead you on your path: Density (grams/ml) = mass/volume
How do you find the density of a salt solution?
Really? Density = mass/(divided by) volume congrats, you just got owned by an 8th grader =)
Why does an egg float when salt is added?
Adding salt to the water increases its density. On adding certain quantity of salt, the density of water becomes greater than that of egg. So by law of flotation, as the mass of water (salted) displaced by egg is greater than its own mass, the egg floats.
Will a boiled egg float if you add salt to water?
Yes, it will eventually. When you add salt to water, you are increasing the density of the solution, but not the volume, because the salt dissolves (dissociates). Since density is mass divided by volume, there is a direct relationship between the solution's mass and its density. They increase together even as the volume remains constant. An egg will float in a salt solultion if the molarity is about 2.5 or above.
What is the equation for mass volume and density?
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
Does adding salt or sugar to water change the density of water?
the sugar makes the density increase so it changes the density in water
How egg float in salt water funfacts?
well an egg can float in salt water because of the mass and density of it makes it easier to float
How much salt is there in salt?
most commonly found on the web: 1/2 teaspoon
A cylindrical box with a volume of 200 cm3 holds 432 g of sodium chloride. calculate the density of the salt?
Density is defined as mass per unit volume. 432/200 gives the density of 2.16 gms/cc. Which happens to be the density of common salt, sodium chloride. Note that to get the density of a salt, the salt in the box has to be a solid lump not a powder which would have a lower density.
