WebCalculate pOH from pH by using the pH + pOH = 14 (at 25 0 C) Then you can calculate the concentration of NaOH solution by pOH = -log10[OH-(aq)] . Then find the required moles of NaOH by the equation of C =n/v . Here C = concentration, n=required moles, v = volume of solution. Now weight is measured by multiplying number of moles and molar mass.
