A student created four solutions by adding 4.00mL, 8.00mL, 12.00mL and 16.00mL of 0.666M NaOH to 12.0mL of 1.00M weak acid. After that the student diluted each of the four solutions to 100.00mL with deionized water. The pH of each solution was 4.615, 5.072, 5.488, and 6.114, respectively.

For all of the four solutions how many moles of base were added?
