Density of alcohol: 0.78945 g/cm^3 (20°C) ?

Density of water: 1.0 x 10?kg/m

1. Density is mass per unit volume. International units for kilograms per cubic meter (kg/m?), in addition to commonly used grams per cubic centimeter (g/cm?). ? For liquids or gases also use kilograms per liter (kg/L), grams per milliliter (g/mL). But g/L is generally not used.

2. Ethanol is an organic matter, commonly known as alcohol, ethanol liquid density is 0.789g/cm?(20 ℃), ethanol gas density of 1.59kg/m? ?

3. The density of water varies with temperature and is closest to 1 at 4 degrees, 0.999

4. The liquid density of ethanol is 0.789g/cm?, the gas density of ethanol is 1.59kg/m?, the relative density (d15.56) is 0.816, and the formula quantity (relative molecular mass) is 46.07g/mol. the boiling point is 78.4°C, melting point is -114.3°C. Pure ethanol is a colorless and transparent liquid with special fragrance and volatile.

5. The physical properties of ethanol are mainly related to the nature of its low carbon straight chain alcohols. Hydroxyl groups in the molecule can form hydrogen bonds, so ethanol viscosity, but also less than a similar relative molecular mass of organic compounds with high polarity.

The refractive index of ethanol is 1.36242 at λ=589.3nm and 18.35°C, which is slightly higher than that of water.

6. Density formula:

ρ=M/V. M=ρV. V= M/ρ.

Commonly used units are: grams/cubic centimeter. g/cm3. kg/cubic meter. kg/m3.

Conversion: 1g/cm3=10-3 kg/10-6 m3=1000 kg/m3. 1000 kg/m3=1g/cm3. 1000 kg/m3=1g/cm3.

Conversion: 1g/cm3=10-3 kg/10-6 m3=1000 kg/m3. 1000 kg/m3=1000 kg/m3. m3=1g/cm3.

2700kg/m3=2.7 g/cm3.
