⚠️ Chemical Safety & Metrology Notice

All solvent densities are standardized at 20°C (68°F) per IUPAC / CRC Handbook 104th Edition and cross-verified against Section 9 of representative Manufacturer Safety Data Sheets (SDS). Volatile organic solvents present flammable and toxic hazards; always follow GHS workplace handling directives.

Frequently Asked Questions

Industrial chemistry and solvent mass-to-volume FAQs.

How many litres is 10 kg of pure acetone?+

10 kg ÷ 0.784 kg/L = 12.755 Litres (12,755 mL). Acetone is 21.6% lighter than water, so 10 kg expands into nearly 12.8 litres of volume.

Why does ethanol density increase as purity drops from 100% to 96%?+

Pure anhydrous ethanol has a density of 0.789 kg/L. Rectified azeotropic ethanol contains 4% dissolved water (1.000 kg/L). Because water molecules form tight hydrogen bonds between ethanol molecules, the volume contracts and solution density rises to 0.806 kg/L.

Why is Dichloromethane (DCM) so much denser than hydrocarbon solvents?+

Dichloromethane (CH₂Cl₂) contains two heavy chlorine atoms (atomic mass 35.45 u each), raising its molecular density to 1.326 kg/L. Unlike acetone or hexane, DCM sinks to the bottom of water separation funnels.

What is the safety implication of solvent vapour density vs liquid density?+

While liquid solvents are mostly lighter than water (0.65–0.90 kg/L), their volatile solvent vapours are 2 to 4 times heavier than atmospheric air (air = 1.0; acetone vapour = 2.0; hexane vapour = 2.97). Evaporated solvent vapours sink and travel along floors to distant ignition sources, requiring low-level explosion-proof exhaust ventilation.
