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

What is Meyer's oscillating disc method?
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.
What is ebullioscopic method?
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
What is the molecular weight of ethyl alcohol?
The formula for ethyl alcohol, or ethanol, is C2H6O.See the Related Questions to the left to determine the molecular weight of any compound, such as ethanol.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the molecular weight and molecular formula of potassium humate?

If you have molecular weight how can you find equivalent weight?
Equivalent weight ofc11h17n3os2 from molecular weight271.402
How molecular weight determined by nmr spectroscopy?
NMR isn't really used to determine molecular weight in general. It can be done for certain oligomers by, for instance, determining the ratio of end-group protons to protons that only occur in the "middle" of the chain.
Why osmotic method for calculation of molecular weight is better than boiling point method?
The osmotic method is better because some solutes and/or solvents are decomposed by the heating required to cause a solution to boil.
What is the molecular weight of vanillideneacetone?
The molecular weight of vanillideneacetone is 192.214g/mol.
What is the molecular weight of sodium nitrate?
Sodium nitrate molecular weight is 84,9947.
