can anyone check my work/ help me figure out how to do this?

Determine the pH of the following solution.

A 4.5 x 10^-3 M HBr solution

My Work:
all I did was -log(4.5x10^-3) and got 2.35 but I am not sure at all how to do this

Answer:

2.35.

Explanation:

∵ pH = - log[H⁺].

[H⁺] = 4.5 x 10⁻³ M.

∴ pH = - log(4.5 x 10⁻³ M) = 2.346 ≅ 2.35.
