How Molecules In 1 Molar Mass Of Water H2o

Moles and mole fraction. A mole (mol) b is an amount (having both number and resultant mass) of something and is defined as the amount that contains exactly the number of entities of that something as there are 12 C atoms in 12 grams of 12 C. This number (currently established as 6.022 140 82 ˣ 10 23 ˣ mol-1 []) is known as the Avogadro number (see the portrait of Avogadro, above right).

Ester names are derived from the parent alcohol and the parent acid, where the latter may be organic or inorganic. Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called "trivial names" e.g. as formate, acetate, propionate, and butyrate, as opposed to the IUPAC nomenclature methanoate, ethanoate, propanoate and butanoate.

Water has a very high specific heat capacity of 4.1814 J/(g·K) at 25 °C – the second highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its molecules. These two unusual properties allow water to moderate Earth’s.
