What is the purpose of measuring density of a liquid w/ sugar, diet soda, and regular soda content?

Probably to determine the amount of dissolved solids (commonly called "Total Dissolved Solids" or "TDS") in it.  Dissolved solids are anything dissolved in the water that will leave a residue when evaporating it to dryness.  \n\nIn this case it will consist primarily of sugar, except for the diet, which will have no sugar.\n\nMore about TDS:  The reason you can detect the density difference between pure water and sugar water, is that most solids will have a higher density than water.  Therefore, when they are mixed or dissolved in the water, they will increase the density.

To determine density you also have to know the temperature.  The colder a substance gets, the more dense it becomes (ie. the particles come closer together).  Water is the one odd ball, it becomes most dense at 4 degree C instead of below freezing like most substances.

The mass of any substance depends on how much you have of it, it is not a fixed amount.\nYou may be thinking of density perhaps?  The density of a substance is equal to its mass divided by its volume (D=m/v), density is the same for a given substance no matter how much you have.\nIf by chance you are talking about density, probably the most important liquid to know would be water with a density of 1 g/mL at room temperature.

If you know the density of the material, you can measure it's volume.  D = M / V.  Therefore, the mass equals the density of the object times the volume.  The weight of the material is its mass times gravity.

Suspect this is what you mean...\n\nSuppose you have 0.500 g of a substance you believe is pure...\nyou analyse it and determine that it contains 0.300 g of the substance you are looking for..\nso your sample is (0.300/0.500) x 100% pure  = 60%

Excellent question.  Unfortunately, I don't have an answer and don't know where to find an answer.\n\nInteresting to note that on one website, the specification for some sets of balls is that each individual ball within a set weigh within one gram of the average of all the balls of that set.  That seems like a pretty high acceptable deviation, and enough to create at least a minute difference in its density, thus creating a higher probability of being at the bottom of the mixing container.

Since you will get the entrained air as part of any volume measurement, you ideally want to find a solvent that it isn't soluble in. If you want the density of it including the entrained air (between granules).\n\nFinally, you can fill the voids between granules to make a solid in solid 'solution' by taking a known material of much smaller particle size and known density and mixing it all together so that the unknown granules are widely dispersed. \n\nPack the mix to get a volume and weigh it. Now, subtract the known volume and weight of the added material to find the unknown volume and weight.

Fehlings solution is used to test for sugar.  Try a diabetic dipstick.

I found a web site with a lab on how to figure out releative density of a given liquid hope it helps.  It has all the instructions and materials needed listed on the site

one generally uses pure water as a base point. other liquids are typically refrenced as lighter or heavier than water.

Does density affect  items when temperature, humidity, and  gravity are changed?

The best way to find the volume of a liquid is just to put it in a liquid measuring device, graduated cylinder or measuring cup. \n\nFor a solid, a displacement test is good when the shape is irregular. \nex. fill a graduated cylinder with enough water to ensure that when you place the object in the water it will be completly submerged. Note the volume. Place the object in the water, the water level will increase. The amount of the increase will be the volume of the object.

There are several uses for this.  Generally for chemistry students the effort teaches them how the measurements are made, good laboratory techniques, and hopefully, some insight into chemistry and the physical sciences.  It doesn't always work, but it makes a good experiment. \n\nFor those who are in the business of using various substances, it is very important to know what their physical properties are, and how they relate to the physical properties of other substances.  Your air conditioner was designed around those measurements, as was your car, paint, furnace, and just about everything that was manufactured around you.  \n\nWhile nature obviously doesn't carefully record properties in a lab book, they are important to how plants and animals work, how hard rocks are, how ice forms, etc.  Without understanding these properties, we can't understand nature or ourselves completely.

Not enough information provided. The density of any carbon fiber product is based apon the requirements of the product and its use. The amount of polymer to fiber ratio is based on that information.
