If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. This site explains how to find molar mass. The reason is that the molar mass of the substance affects the conversion. To complete this calculation, you have to know what substance you are trying to convert. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.Ī common request on this site is to convert grams to moles. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.įinding molar mass starts with units of grams per mole (g/mol). grams Chromium(III) Sulfate to centimol.grams Chromium(III) Sulfate to molecule.grams Chromium(III) Sulfate to millimol.grams Chromium(III) Sulfate to micromol.Moles Chromium(III) Sulfate to grams, or enter other units to convert below: Enter two units to convert From: Other chromium(III) hydroxides have been reported.You can do the reverse unit conversion from Most important commercially is basic chromium sulfate, which is thought to be SO 4 (CAS#3). It results from the partial neutralization of the hexahydrates. Further heating yields the anhydrous sulfate.Ī variety of other chromium(III) sulfates are known, but also contain hydroxide or oxide ligands. It is obtained by heating the 18H 2O material above 70 ☌. 15(H 2O), (CAS #1) is a green solid that also readily dissolves in water. Hydrated chromium(III) sulfate, Cr 2(SO 4) 3.Six of the 18 water molecules in this formula unit are water of crystallization. The formula of this compound can be written more descriptively as 2(SO 4) 3. 18H 2O, (CAS #1) is a violet solid that readily dissolves in water to give the metal aquo complex, 3+. Anhydrous chromium(III) sulfate, Cr 2(SO 4) 3, (CAS #1) is a violet solid that dissolves in water upon addition of a reducing agent, which generates chromium(II) sulfates.Other chromium(III) hydroxides have been reported. ![]() Most important commercially is basic chromium sulfate, which is thought to be SO4 (CAS#3).
