what is "equivalent molecular mass " means and how to determine it from mole fraction ????

Have you studied the definitions:

http://en.wikipedia.org/wiki/Mole_fraction

http://en.wikipedia.org/wiki/Molecular_mass

Could you be more specific.Giving definition may not help you depending on what you need to know.

if we have a mixture of total n mole(say x mole a ,y mole b,z mole c).and x+y+z=n.from there we can find the mole fraction that means moles of each components in 1 mole mixture.then we can multiply each mole fraction with each molecular mass and add them up.and it is called equivalent molecular mass. so my question is does equivalent molecular mass means mass of 1 mole of that mixture with respect to its components???????

I don't know this whole thing but in High school I used equivalent mass to calculate Normality.There is also sth called number of equivalents.

Sorry I couldn't help but if you need sth like this or equivalent mass I used in solution chemistry I can help you.
