Question: feed stream entering into a flash vessel at 50 0 C and 10 bar contains 17.3 wt% propane, 22.7 wt% iso-butane, 38.5 wt% propylene and

feed stream entering into a flash vessel at 50 ⁰C and 10 bar contains 17.3 wt% propane, 22.7 wt% iso-butane, 38.5 wt% propylene and 21.5 wt% benzene. The mass flow rate of the feed is 833.0 kg/hr. Inside the flash vessel the pressure suddenly drops causing the liquid to separate into two streams, a vapour and liquid stream. The liquid stream has a composition of 14.8 wt% propane, 25.2 wt% iso-butane, 30.8 wt% propylene and 29.2 wt% benzene. While the composition of the vapour stream is not fully known, it is known that the stream contains 24.1 wt% propane.

a) Using the known stream values, calculate the complete composition of the vapour stream.

please i need all steps of the calculations not just basic explanation without any calculation, also do not give the same answer as the one uploaded before because it is wrong.
