Answer: 2.223

Explanation:

HClO4, also known as perchloric acid, is a very strong. This means we can assume that complete dissociation occurs.

This means that:

[H+] = [HClO4] = 0.00598

pH = - log[H+]

pH = - log[ 0.00598] = 2.223

Note: The base of the log is 10 (conventionally we don't write the base if it is 10)
