An aqueous solution contains 0.100 m naoh at 25.0 °c. the ph of the solution is

pH = 13.00

Explanation:
pH measures the concentration of H+ ions in the solution.
Since the given solution is basic, therefore, we cannot get the pH directly.
We will have to calculate the pOH first and then get the pH as follows:
1- getting the pOH:
pOH measures the concentration of OH- ions in the solution. It can be calculated as follows:
pOH = -log[OH-]
Since the given solution is basic, therefore [OH-] is equal to the
molarity = 0.1 m
Substitute to get the pOH as follows:
pOH = -log[0.1] = 1.00

2- getting the pH:
pH + pOH = 14
pH + 1 = 14
pH = 14-1
pH = 13.00

Hope this helps :)

Idon't know hope someone you
