Chemical formula. KOH Molar mass: 56.105 g·mol ... A 3–5% aqueous solution of KOH is applied to the flesh of a mushroom and the researcher notes whether or not the ...
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
Dimethyl sulfate (DMS) is a chemical compound with formula (CH 3 O) 2 SO 2. As the diester of methanol and sulfuric acid, its formula is often written as (CH 3) 2 SO 4 or Me 2 SO 4, where CH 3 or Me is methyl. Me 2 SO 4 is mainly used as a methylating agent in organic synthesis. Me 2 SO 4 is a colourless oily liquid with a slight onion-like odour.
Potassium sulfide is an inorganic compound with the formula K 2 S. The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH). Most commonly, the term potassium sulfide refers loosely to this mixture, not the anhydrous solid.
Potassium bisulfite (or potassium hydrogen sulfite) is a chemical mixture with the approximately correctly mentioned formula chemical formula KHSO 3.Potassium bisulfite in fact is not an actual compound, [1] but a mixture of salts that dissolve in water to give solutions composed of potassium ions and bisulfite ions.
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3.Sodium bisulfite is not a real compound, [2] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
For example, 50 g of zinc will react with oxygen to produce 62.24 g of zinc oxide, implying that the zinc has reacted with 12.24 g of oxygen (from the Law of conservation of mass): the equivalent weight of zinc is the mass which will react with eight grams of oxygen, hence 50 g × 8 g/12.24 g = 32.7 g.
Natural polyphenols molecular formulas represent a class of natural aromatic organic compounds in which one or more hydroxy groups are attached directly to the benzene ring, generally formed from C, H and O. [1] The entries are sorted by mass.
