Molarity = moles solute/Liters solution
get moles NaOH
0.240 grams NaOH (1 mole NaOH/39.998 grams)
= 0.0060 moles NaOH
----------------------------------as one to one OH- has this many moles also
Molarity = 0.0060 moles OH-/0.225 Liters
= 0.0267 M OH-
-----------------------
-log(0.0267 M OH-)
= 14 - 1.573
= 12.4 pH
