the formula of relative lowering of vapour pressure that we have studied is pi - p /pi ie, formula is ie, pi – p/p =n2/n1 .but in some problems formula ,the denominator is p instead of pi. in which cases should we take like that ie, pi – p/p =n2/n1

Dear student 
Do not confuse in that , 
The denominator is pi means the vapour pressure of pure solvent.
Good Luck
