This well known formula should lead you on your path: Density (grams/ml) = mass/volume
The amount of salt that can dissolve in 20mL of water depends on the solubility of the salt at that temperature. For common table salt (sodium chloride), approximately 36 grams can dissolve in 20mL of water at room temperature.
Yes, a solution is considered concentrated when there is a large amount of solute (salt in this case) dissolved in a given amount of solvent (water in this case). With 20ml of salt in 50ml of water, the concentration of the solution would likely be high.
The density of the object is calculated by dividing its mass by its volume. In this case, the density would be 4000g / 20ml = 200 g/ml.
To determine the density of a substance, you need to divide the mass by the volume. In this case, the density would be 40 grams / 20mL = 2 grams per milliliter (g/mL). Density is a physical property that describes the amount of mass per unit volume of a substance.
It is 0.87 g/mL.
20ml
20ml - 0.2ml = 19.8
Approx. 7,2 g at 20 0C.
If I understand the question correctly %Salt=mass salt/(mass salt+Mass water) *100 If these are known all is well... Measure your salt and water on a scale and input the results for the %
The mass of the table salt can be calculated by subtracting the mass of the container from the combined mass of the table salt and the container. So, 124g - 9g = 115g. Therefore, the mass of the table salt is 115g.
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.
The mass of salt reclaimed should be the same as the mass of salt that was put into the solution.
