A feed containing equimolar quantity Of methanol and water
Is mixed with 10 moles of a 40% mole aqueous methanol stream . The mixture enters a separationunitt that creates two streams
A top stream exits that contain 70% mole methanol and the rest water the other stream which is 70 moles enters a second separation unit

A top stream exists the second unit as a 50% methanol 50% water mixture . The other stream is unknown
If the fresh feed to the system
If the fresh feed to the system is 100 moles (the equimolar mixture) and the two top streams exiting the separation units have the same flow

Find the molar flow and the composition of the other stream exiting the second separation unit
