water.
Liter is a measure of volume. Volume = mass/density.
Density is the measure of mass divided by volume. To know the density of whatever you're referring to, we would need a lot more information.
Solubility is a measure of how well a solute can dissolve in a solvent at a given temperature.
The solute would be iodine, and the solvent would be tincture
pentane will be good solvent for naphthalene.
water.
water b/c it is insoluble in water. it is soluble in cyclohexane and sparingly soluble in ethyl alcohol.
The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.
to for example measure the pressure under water
Push it down to measure the volume.
Liter is a measure of volume. Volume = mass/density.
Solubility of the material in the given solvent. EG, salt in water at 25 deg. C would be such an experiment.
That depends what you want to measure about it: its weight, its color, its density, etc.
Naphthalene is soluble in alcohols, benzene, ammonia, carbon disulfide.
Density is the measure of pounds per square inch it would be important if you designed tanks because you would need to know what density of the tanks armor it would need to be same as in a submarine.
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
