What is the specific gravity of white vinegar?
Specific Gravity of Liquids
|Acetic acid 5% - vinegar||59||1.006|
|Acetic acid - 10%||59||1.014|
|Acetic acid - 50%||59||1.061|
|Acetic acid - 80%||59||1.075|
Water has a density of about one gram per cubic centimeter (depending a little on temperature and pressure). Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. In general, dissolving stuff in water makes it more dense, making vinegar the densest of the three.
- They should conclude that the alcohol floats because it is less dense than the oil. Water sinks because it is more dense than oil. Explain that, just like solids, liquids are made from atoms and molecules, which have a certain mass and size.

- The density of raw milk depends on its composition and temperature and can usually – literature data vary slightly – be found in the range of 1.026 g/cm3 – 1.034 g/cm3 at 20°C.
- A vinegars "grain" is a number used to specify its acetic content. Grain is 10 times the percent of acetic acid present. For example, all Heinz® bottled vinegars are at least 50 grains, which means they contain at least 5 percent acetic acid and are called 5 percent vinegars.
- Vinegar is made up of mostly water plus acetic acid (HC2H3O2) and maybe some herbs and spices. It is the acetic acid that gives vinegar its characteristic taste and odor. The optimum amount of acetic acid in vinegar is between 4 and 5 percent by weight.
- Acetic acid that contains a very low amount of water (less than 1%) is called anhydrous (water-free) acetic acid or glacial acetic acid. The reason it's called glacial is because it solidifies into solid acetic acid crystals just cooler than room temperature at 16.7 °C, which ice.
Find the molarity of acetic acid in vinegar sample. Assuming that the density of the vinegar solution is 1.00 g/mL and that all of the acid titrated comes from acetic acid, determine the % by mass of acetic acid in the vinegar. The minimum for acetic acid content in vinegar is often set at 4.75%.
