A chemist dissolves 9.07g of NaOH in enough water to make 236. mL of solution.?

What can she expect the pH of the solution to be?

Molecular weight NaOH = 40 g/mol
9.07 g / 40 = 0.227 moles NaOH
NaOH is a strong base :
NaOH >> Na+ + OH-
[OH-] = 0.227 / 0.236 L = 0.961 M
pOH = - log 0.961 = 0.0173
pH = 14 - pOH = 13.98
