An ideal binary solution of A and B has a vapour pressure of 900 torr. It is distilled at constant temperature till of the original amount is distilled. If the mole fraction of 'A' in the residue and the mole fraction of 'B' in the condensate are 0.3 and 0.4, respectively and the vapour pressure of residue is 860 torr, then (1 bar = 750 torr) :
The mole fraction of ' ' in the initial mixture is :
Answer:
0.50
