To accurately calculate the molarity of an EDTA solution you need to determine the number of moles present and liters of solution. Take these two totals and divide them to determine molarity.
The molecular weight of EDTA is 292.24g/mol
EDTA (as acid: H4EDTA): C10H16N2O8 Molar mass: 292.24 g/mol
Sometimes the disodium salt (Na2EDTA) is used, then it is 44 g/mol more: 336
Ethylenediaminetetraacetic acid, widely abbreviated as EDTA, has a molecular mass of 292.24 g/mol
It has a molecular weight of 21,600 Daltons
Equivalent weight ofc11h17n3os2 from molecular weight271.402
Petrol is an extremely complex mixture of organic compounds; each compound has his molecular weight. A molecular weight for a mixture is a nonsense.
Molecular weight is just an older term for molar mass. They are the same.
The molecular weight for mineral calcite is 100.09. Calculated from the formula (Mol_Wt_Calc).

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.
EDTA has a molecular weigh of 292.24g/mol. So if you want to make 1 litre for example of 0.5M EDTA, you'd weigh out 292.24*0.5 or 146.12g of EDTA and dissolve and fill to 1 litre with solvent

The molecular weight of vanillideneacetone is 192.214g/mol.
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
Sodium nitrate molecular weight is 84,9947.
Sodium nitrate molecular weight is 84,9947.
the given molecular weight is divided by volume
Petrol is an extremely complex mixture of organic compounds; each compound has his molecular weight. A molecular weight for a mixture is a nonsense.
