The molecular formula C 6 H 8 O 6 (molar mass: 176.124 g/mol) may be: Ascorbic acid (vitamin C) Erythorbic acid; Glucuronolactone; Propane-1,2,3-tricarboxylic acid;
Heroin users are known to use ascorbic acid as a means to convert heroin base to a water-soluble salt so that it can be injected. [31] As justified by its reaction with iodine, it is used to negate the effects of iodine tablets in water purification. It reacts with the sterilized water, removing the taste, color, and smell of the iodine.
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
For example, water has a molar mass of 18.0153(3) g/mol, but individual water molecules have molecular masses which range between 18.010 564 6863(15) Da (1 H 2 16 O) and 22.027 7364(9) Da ( 2 H 2 18 O).
The molecular formula C 6 H 8 O (molar mass: 96.13 g/mol, exact mass: 96.05751 u) may refer to: Cyclohexenone; 2,5-Dimethylfuran; 2,3-Dimethylfuran; 2,4-Dimethylfuran;
Water molecules stay close to each other , due to the collective action of hydrogen bonds between water molecules. These hydrogen bonds are constantly breaking, with new bonds being formed with different water molecules; but at any given time in a sample of liquid water, a large portion of the molecules are held together by such bonds.

Drinking under a glass of wine a day while on the Mediterranean diet might help the heart, a new study finds. Experts aren’t so sure.
The gaseous state of water is lighter than air (density 0.804 g/L at STP, average molecular mass 18.015 g/mol) due to water's low molar mass when compared with typical atmospheric gases such as nitrogen gas (N 2). It is non-flammable and much cheaper than helium. The concept of using steam for lifting is therefore already 200 years old.
