The mass of salt depends on the quantity being measured. For example, 1 teaspoon of table salt has a mass of about 6 grams. The density of salt is approximately 2.16 grams per cubic centimeter at room temperature.
The density of the salt solution is calculated by dividing the mass of the solution by its volume. In this case, the density would be 234 g divided by 210 mL, which equals 1.114 g/mL.
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.
Mass density is a measure of how much mass is contained in a given volume of a substance. It is calculated by dividing the mass of an object by its volume. The formula for mass density is: Density Mass / Volume.
You can find the mass of a substance by using the formula mass = density x volume. Multiply the density of the substance by its volume to calculate the mass.
No, density is defined as mass per unit volume. Mathematically, density = mass/volume.
Density = Mass/Volume As salt(mass) increases and the volume remains the same, density also increases.
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.
The density of the salt solution is 1.14 g/ml. This is calculated by dividing the mass (57.0 g) by the volume (50.0 ml).
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.
To find the volume of the salt, we use the mass of kerosene displaced. Since 7.6 g of kerosene is displaced, the volume of the salt can be calculated using the density of kerosene: [ \text{Volume of salt} = \frac{\text{mass of kerosene}}{\text{density of kerosene}} = \frac{7.6 , \text{g}}{0.83 , \text{g/cm}^3} \approx 9.15 , \text{cm}^3. ] Next, we find the density of the salt using its mass and the calculated volume: [ \text{Density of salt} = \frac{\text{mass of salt}}{\text{volume of salt}} = \frac{20 , \text{g}}{9.15 , \text{cm}^3} \approx 2.19 , \text{g/cm}^3. ]
The density increases as the mass of the solution increases but its volume remains the same.
The density of the salt solution is calculated by dividing the mass of the solution by its volume. In this case, the density would be 234 g divided by 210 mL, which equals 1.114 g/mL.
This well known formula should lead you on your path: Density (grams/ml) = mass/volume
Really? Density = mass/(divided by) volume congrats, you just got owned by an 8th grader =)
1000 ml of pure water has a density of 1 g/ml, resulting in a mass of 1000 grams. When C grams of salt is added, the total mass increases to 1000 + C grams while the volume remains approximately the same at 1000 ml. Therefore, the density of the water with salt is greater than that of pure water, as density is mass divided by volume, leading to a higher density due to the increased mass.
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.
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.
