A gas stream (stream 1) of ethylene (mass fraction 0.40) and propylene (mass fraction 0.60) enters a separator. The entering stream has a flowrate of 1000 m3/h. You can assume that this is an ideal gas at 25 C and 1 bar. There are two exit streams, stream 2 with mostly purified ethylene and stream 3 with mostly purified propylene. Stream 2 recovers 93% of the original mass of ethylene fed into stream 1. The mass fraction of ethylene in stream 3 is 0.1. What is the mass flowrate of outlet stream 3, and what is the mass fraction of propylene in Stream 2
