Question

A 1-L unbuffered solution needs the pH adjusted from 4.5 to 2.5. How many mL of 12 molar HCl solution need to be added to reduce the pH?

Report your answer using exponential notation to two decimal places! For example 100 would be 1E2, or 0.001 would be 1e-3

For this question, assume the volume of HCl being added is negligible and the total volume of the solution does not change.
