The specific gravity of ethanol is 0.794. This is for pure 100% ethanol. Specific gravity is the ratio of the density of a substance compared to the density of water. For example, water weighs 8.33 lb/gal at standard conditions (60 deg F). Ethanol weighs 6.61 lb/gal at standard conditions (60 deg F). Therefore, the specific gravity of ethanol is 6.61 divided by 8.33, equals 0.794.
A person can verify this result (0.794) by very fundamental experimental testing. Get a gallon of pure water and weigh it precisely. THIS will yield the number 8.33 lbs. Then do the same for ethanol; weigh a gallon of pure ethanol. This will yield the number 6.61 lbs. VOILA! 6.61 divided by 8.33 equals 0.794.
I did NOT actually do this weighing of the two liquids, but I COULD! I instead looked the values up in a standard reference book. My copy of "The Data Book on Hydrocarbons", also commonly referred to as 'the Maxwell data book', is a very familiar book to any one who works around the oil industry, as I did for 38 years.
Water is taken as the base substance for measuring relative density. The relative density of water is 1.0, but that for Mercury, which is 13.6 times as heavy as water (provided the same volume of each is weighed. So we say that the relative density of mercury is 13.6
Another way of saying the same thing is to compare the density of substances. Now the density of water is 1 gram per cubic centimetre (cc).
One cc of mercury weighs 13.6 grams, so we say that its density is 13.6gms/cc
Density is really a measure of how closely the atoms or molecules of a substance are packed together. Somewhat similar to the density of population of a country. I don't know the exact figures but the density of population for England (given as an average of the number of people in each square mile) would be much higher than the density of population for the Sahara Desert.
no @ 20 degrees celsius the density of water is 0.998
@ 20 degrees celsius the density of ethanol is 0.789
units are g/centimetres cubed

What is the Specific gravity of ppc?
Specific gravity of ppc is 3.15
What will be the effect on specific gravity of cement if some of the sample is lost after weighing?
There is no effect on the specific gravity if some of the sample is removed. The amount of mass will change, but it will still have the same specific gravity. It is basically a density. The specific gravity of 1lb of cement is the same as the specific gravity of 100lbs of cement, you just have more cement.
What is the purpose of conducting specific gravity test?
Specific gravity refers to the ratio of the density of a substance to the density of a reference substance. The purpose conducting specific gravity test is to determine if the test fluid will be heavier or lighter than the standard fluid.
What is the specific gravity of portland cement?
According to ASTM C188 the specific gravity of Portland cement is roughly 3.15According to ASTM C188, the specific gravity of portland cement (without voids between particles) is about 3.15. In other words, portland cement is about 3.15 times heavier than water.
Are specific gravity of the material will give effect to strength of concrete?
The specific gravity of materials tell us how many times is the material heavier than water. The higher the specific gravity of a material the higher the density of concrete made with and the higher will be the force require to crush it and the higher will be the corresponding strenght of the concrete
What is the Specific gravity of alcohol 190?
The specific gravity of alcohol 190, which is pure ethanol, is typically around 0.8161 at 20 degrees Celsius. This value indicates that ethanol is less dense than water at that temperature, as the specific gravity of water is 1.
Which takes up greater volume 1000 g of water or 1000 g of ethanol?
The 1000 grammes of ethanol will occupy a greater volume because its specific gravity is lower than that of water. s.g. water = ~1.0 s.g. ethanol = ~ 0.794
What is the simple way to test the purity of ethanol after distillation in fermentation?
One simple way is to measure the specific gravity of the ethanol using a hydrometer. Another method is to use a simple alcoholmeter to measure the alcohol content. You can also use a refractometer to measure the refractive index of the ethanol, which can indicate its purity.
How would you know if the recovered ethanol is pure?
The purity of recovered ethanol can be determined by conducting a distillation test to separate out impurities and measure the ethanol content. The purity can also be verified using methods such as gas chromatography or mass spectrometry to analyze the chemical composition of the recovered ethanol. Testing the specific gravity or conducting a simple flame test can also indicate the presence of impurities in ethanol.
What is the specific gravity for aluminum?
Aluminum has no specific gravity, at least by the current definition of gravity.
What is the Specific gravity of ppc?
Specific gravity of ppc is 3.15
What is the specific gravity of mica?
mica has the specific gravity of 2.88
What is the Specific gravity of acetone?
The specific gravity of acetone is approximately 0.79 at 20°C.
How do you calculate the alcohol percentage in home brew beer when you do not have an initial specific gravity reading?
Ok, so you forgot to take an original gravity reading (O.G.). Hopefully you brewed with a kit or a recipe that tells you the anticipated O.G. Get that number and then when your homebrew finishes get the final gravity reading (F.G.). Calculate the alcohol percentage with this calculation: % ABV = ((anticipated O.G.) - (F.G.)) / (specific gravity of ethanol) % ABV = ((anticipated O.G.) - (F.G.)) / 0.789
What is the api gravity for ethanol?
The API gravity of ethanol is approximately 20.7 degrees at 60°F (15.6°C). This measurement indicates the density of ethanol compared to water, with values below 10 indicating a substance that is heavier than water and values above 10 indicating a substance that is lighter.
What is the quartz specific gravity?
The specific gravity of quartz is nearly 2.65.
