Answer:

2.89

PLATO ANSWER!

Explanation:

pH = -log[H3O+]

pH = -log(1.3 × 103)

pH = -2.89

In the given concentration, the base of 1.3 has two significant figures. So, the answer is given to two places after the decimal point because, for logarithms, the number of significant figures equals the number of digits shown after the decimal point.
