Another example of the apparent molar volume of the second component is less than its molar volume as a pure substance is the case of ethanol in water. For example, at 20 mass percents ethanol, the solution has a volume of 1.0326 liters per kg at 20 °C, while pure water is 1.0018 L/kg (1.0018 cc/g). [5]
The number of millilitres of pure ethanol is the mass of the ethanol divided by its ... where 46.069 is the molar mass of ethanol and 180.156 is the molar mass of ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.

Because chloroform can react with oxygen to form phosgene, chloroform can be stabilized for storage by adding 1 part (by mass) of ethanol to 100 parts (by mass) of chloroform, so that any phosgene that forms is converted into diethyl carbonate. 2 CH 3 CH 2 OH + COCl 2 → CO 3 (CH 2 CH 3) 2 + 2HCl. It can also be made by the alcoholysis of urea ...
