why is mole fraction of binary solution unity? |
| Answer» Let us consider a binary mixture of A and B. let the number of moles of A and B bee nA and nB respectively, thenxA = nA/(nA+nB)xB = nB/(nA+nB)Here, xA+xB = nA/(nA+nB) + nB/(nA+nB)xA+xB = 1.The sum of the mole fractions of all the components in binary solution system must be equal to unity. | |
