What concentration was the perchloric acid?

#### Explanation:

Perchloric acid is a STRONG acid....that completely dissociates to give stoichiometric hydrogen ion...

$H C l {O}_{4} \left(a q\right) + {H}_{2} O \left(l\right) \rightarrow {H}_{3} {O}^{+} + C l {O}_{4}^{-}$

And if we had $1.00 \cdot m o l \cdot {L}^{-} 1$ perchloric acid the concentration would be...

$\frac{50 \cdot m L \times {10}^{-} 3 \cdot L \cdot m {L}^{-} 1 \times 1.00 \cdot m o l \cdot {L}^{-} 1}{150 \cdot m L \times {10}^{-} 3 \cdot L \cdot m {L}^{-} 1} = 0.33 \cdot m o l \cdot {L}^{-} 1$

And now $p H = - {\log}_{10} \left[{H}_{3} {O}^{+}\right] \equiv - {\log}_{10} \left(0.333\right) = 0.48$.
