Equivalent weight = Molar mass of a substance/electrical charge of the ions (positive or negative) formed in solution
Also the equivalent weight of a substance react with 1 mole of hydrogen.
Today this expression is rarely used.
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
Equivalent weight of potassium dichromate = Molecular mass/6 = 294,185/6 = 49,0308
H2O2 was an equivalent weight of 34
The equivalent weight of boric acid is 20,61 g.
The unit formula for sodium bromide is NaBr. There is one sodium ion and one bromide ion. Add the atomic weights from the periodic table for sodium and bromine. This will give you the formula weight. Atomic weight Na = 22.989770 Atomic weight Br = 79.904 Formula weight NaBr= 22.989770 + 79.904 = 102.894 Save
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
the sum of the atomic weights for all the atoms in the formula
Equivalent weight = Molar mass of a substance/electrical charge of the ions (positive or negative) formed in solution Also the equivalent weight of a substance react with 1 mole of hydrogen. Today this expression is rarely used.
Sulfuric acid has a formula weight of 98 - but it has two protons and thus a functionality of two. Equivalent weight = molecualr weight/functionality so sulfuric acid is 98/2 = 49 eq wt
Equivalent weight of potassium dichromate = Molecular mass/6 = 294,185/6 = 49,0308
Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.
there is no formula discovered especially for the weight of flat
Equivalent weight ofc11h17n3os2 from molecular weight271.402
the equivalent weight of chlorine is 35.453, which is also it's atomic weight.
EDTA (Na2H2EDTA.2H2O) is 374.24g/mol Be careful not to confuse pure EDTA with the required EDTA used in the lab. C10H12N2O8•4Na is the correct chemical formula for lab use and is the MW above.
Formula: Distance/Time
Formula of oxalic acid is H2C2O4.2H2O. Therefore, the equivalent weight of the acid is molecular weight divided by n-factor = 126/2 = 63.
