Answer 3

You are provided with the molarity (no. of moles per unit volume) of the NaOH, now calculate its pH using the formula
\[pOH=-\log_{10} (Molarity of the base)\]
then use the relation pH + pOH = 14 and use the value of the calculated pOH and find pH.
pH = 14 - pOH

Answer 4

ok...thank you! I get that method......
