The pH of NaOH will depend on the concentration of NaOH.
Without the concentration of NaOH, one can only state that it has pH of greater than 7, since NaOH is basic.
NaOH is considered to be completely soluble so the concentration of OH- will equal to the concentration of NaOH in Molarity.
Once [OH-] is determined, you can use the equation:
pOH = -log[OH-]
Once pOH is determined, use following equation:
14 - pOH = pH
That will give you the pH of the NaOH at given concentration.

The pH of a sample of sodium hydroxide is based on its concentration, specifically its molarity. It is how many moles/liter that is the molarity.
For NaOH, actually yes, you'll have to calculate the pOH. The -log[molarity] is the pOH. The pH is 14-pOH in water. My mistake.

pH is the negative log of hydrogen ion cocentration in moles per litre.to find pOH
pOH=14 - pH
FOR NaOH; pH=14 cause pOH=0 FOR 1 MOLAR NaOH
