Citric acid has the formula

and is tribasic acid, forming the tri$-$sodium salt

on complete neutralisation with sodium hydroxide.

A $25\mathrm{.}0mL$ sample of a concentrated citrus fruit cordial component $($e$.$g$.$ for lime juice$),$ used in the food & drinks industry, was

diluted to $250mL$ in a graduated volumetric flask.

A $25\mathrm{.}0mL$ sample of this diluted solution, required, on average, $22\mathrm{.}5mL$ of a standard $0\mathrm{.}100$ molar sodium hydroxide solution

using phenolphthalein indicator for the titration end$-$point.

Assuming all the acid in the cordial was citric acid, calculate the concentration of the acid in $\frac{g}{m}L$ in the original solution.
