Dear Experts,


For binary mixtures, min number of stage can be calculated using fenske equation.

My question is , can i use weight fraction instead of mole fraction in this equation ? 

this question is comes into the picture because sum of weight fraction and mole fraction will be 1 in binary mixture. 


Please share your comments for the same.

Thank you in advance

Your question is easy enough to test. If you do not calculate the exact same stages, then you will know for sure.
