The molecular weight of vanillideneacetone is 192.214g/mol.
the given molecular weight is divided by volume
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature
which is the average molecular weight 603 Mobiltherm?
The molecular weight of the carbonate ion is 60 grams per mole.
Meyer's oscillating disc method is a technique used to determine the molecular weight of a polymer by measuring the change in weight of a solution containing the polymer as it oscillates at a specific frequency. This method allows for accurate determination of molecular weight and can be used to study the size and structure of macromolecules.
Ebullioscopic method is a physiochemical method to determine the molecular weight of compounds....."when a non volatile solute is added to pure solvent or liquid the boiling point of the pure solvent is increased and the elevation in the temperature is related to the molecular weight of solute"this is given by formula:M=1000Kew/(ΔTW)WHERE Ke is the molal elevation constant,w is the weight of solute, W is the weight of solvent and M is the molecular weight................................................irfan ali bughio from uni of sindh,,,,,,,,,allama i.i qazi institute of chemistry..ayaan622@yahoo.com
It has a molecular weight of 21,600 Daltons

The osmotic method is better because some solutes and/or solvents are decomposed by the heating required to cause a solution to boil.
The molecular weight of vanillideneacetone is 192.214g/mol.
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.
The atomic weight (not molecular) of tantalum is 180,947 88(2).
