Correct answer is already given in the question I need complete stepwise solution and reason how he got the shown correct $$answer$.$ Please dont use the chat gpt to get the answer beacuse it gives incorrect answer correct answer will be upvoted and appreciated and incorrect answer will be reported

A CSTR is being used to produce chemical B using the following reaction:

AlongrightarrowB

The reactor has one inlet and one outlet and operates at a constant density

of $55l\frac{b_m}{f}{t}^3.$

The fractional conversion of species $A$ is $0\mathrm{.}3$

The mass flow rate into the reactor is $13\mathrm{.}2k\frac{g}{h}r$ and the concentration of

species A leaving the reactor is $16\mathrm{.}6$gmol$\frac{e}{L}.$

What is the entering concentration of species $A$ in units of gmol$/$L$?$
