| Answer and explanation: the molar mass of Al2 (SO4) 3 is 342.14 g / mol.
Permit. Aluminum sulphate is a chemical compound with the formula Al2 (SO4) 3. It is soluble in water and is mainly used as a coagulant (promotes the flow of particles by neutralizing the charge) in drinking water purification and water treatment plants wastewater, as well as in the newspapers. Production.
The basic SI unit for the amount of substance is Temol. 1 mole corresponds to 1 mole of Al2 (SO4) 3 or 342.150876 grams.
Use the molecular formula to find the molecular weight, to get the number of moles, divide the mass of the mass by the molecular weight of the compound, expressed in grams.
The basic SI unit for the amount of substance is Temol. 1 mole corresponds to 1 mole of BaSO4 or 233.3896 grams
Al2 (SO4) 3
The molar mass of Al2 (SO4) 3 is 342.14 g / mol. Two aluminum atoms: 2 (26.98 g / mol) = 53.96 g / mol. Three sulfur atoms: 3 (32.06 g / mol) = 96.18
A molecular formula consists of the chemical symbols of the constituents, followed by numerical inscriptions that describe the number of atoms for each element present in the molecule. The empirical formula represents the simplest general relationship between the atoms of a compound
Answer and explanation:
96.06 g / mol
The mass of the oxygen atoms is 16 grams per mole. 1 mole of O2 contains 2 moles of oxygen atoms or 32 grams The molecular masses of molecules are always the molar masses of all atoms added together.
Sulphate. Sulfation is a very weak base, while HSO4 is a fairly strong acid with Ka = 0.01. On the other hand, H2SO4 is a very strong acid. Since it is such a weak base, sulfation in aqueous solution is subject to insignificant hydrolysis.
Sulfate or sulfate (see notation) is a polyatomic anion with the empirical formula SO2−4. Sulfate is the IUPAC recommended spelling, but sulfate is used in British English. Salts, acid derivatives and sulphate peroxides are widely used in industry.
Sulfate is a compound that contains a sulfur atom surrounded by four oxygen atoms. The sulfate compound forms an atetrahedral bonded arrangement. The sulfate forms a salt when it is converted to sulfuric acid. It can chelate with metals.
Aluminum sulfate is ionic. It consists of the aluminum ion and the polyatomic sulphate ion. The simplest formula for an ionic compound with a zero net charge in this case is ionic aluminum sulfate.
SO4 is a sulfate ion and (SO4) 3 means there are 3 sulfate ions. The number 3 for Al2 (SO4) 3 means that the chemical formula contains three times as many atoms and ions. The number of ions is easy to calculate. There are a total of 15 ions (3x5).
The value of the radical. For example, H2SO4 has two hydrogen atoms, so the valence of the sulfate is two. Since sulfate can bond to two positive hydrogen atoms, its value is the opposite charge and is often expressed as 2.
Sulphate is an oxo-anion of sulfur which is obtained by deprotonating the two OH groups in sulfuric acid. Acts as a human metabolite and as a metabolite of Saccharomyces cerevisiae. It is sulfur oxanion, sulfur oxide, inorganic anion and divalent inorganic anion.
The angle between the electron pairs in a tetrahedral arrangement is 109.5 °.
Hydrogen has an atomic weight of 1008 (rounded to the third decimal place) and always assumes valence 1 in compounds, so its equivalent weight is 1008. Oxygen has an atomic weight of 15,999 and always assumes that valence 2 in compounds compounds is 7.9999.
