Consider a reactor designed to produce chemical C based on the following irreversible reaction: $2$ A $+$ B $->3$C

The reactor has the following characteristics:

$$ It has a single inlet and outlet

$$ The density of the reactant$/$product streams is constant

$$ The entering concentration of C is $0\mathrm{.}26$ gmol$/$L

$$ The volumetric flow$-$rate entering the reactor is $67\mathrm{.}3$ L$/$s$.$

$$ The consumption rate of A is $4\mathrm{.}47$ gmol$/$s$.$

What is the leaving concentration of component C in units of gmol$/$L$?$
