pH is a symbolic representation of:
and for water we now that:
that means the text give us the information to calculate the concentration of protons and therefore the concentration of ions OH-:
therefore the concentration of OH- can be calculated:
but they are not asking about the concetration of OH- they ask about concentration of Ba(OH)2 and for that we need to know the disolution stechiometry
Whic mean the concentration of Ba(OH)2 is half the concentration of OH-:
