There are three properties that can be used and they are the boiling point elevation, freezing point depression, and osmotic pressure. The molar mass is equal to mass of the unknown divided by the moles of the unknown.

∙ 13y agoUsing a Periodic Table, find the elements in the molecule you are trying to weigh, for example in NaO you would need to find sodium (Na) and oxygen (O). Then find the weight for those elements under (or above on some tables) the element symbol (the letter(s)). Multiply the weight by the number of the element, which is shown by the small number to the right and below the symbol on the molecular formula. Add all the elements together after you have multiplied each separate element with its number and weight, and you will have the molecular weight.

How will determine Molecular weight by Landsberger method?
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

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.

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.
