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.

∙ 12y agoWater 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.

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 api gravity for ethanol?
46.49
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 diamonds specific gravity?
