Explanation:

$\to HCl \ mol = \frac{23.1 \ g}{36.5 \frac{g}{mol}} = 0.633 \ mole\\\\\\\to HCl \ molarity = \frac{ 0.633 \ mole }{1.25 L} \\\\$

$=0.5064 \ m$

$HCl +H_2O \longrightarrow H_3O^{+} + Cl^{-}\\\\\\$

$[H_3O^{+}] =[HCl] \\\\\to [H_3O^{+}] =0.5064 \ m \\\\\to PH =-\log [H_3O^{+}] \\\\$

$= -\log (0.5064)\\\\= 0.295 \\\\=0.3$
