The answer is Kepler's first law. Kepler's first law - sometimes referred to as the law of harmonies - compares the orbital period and radius of orbit of a planet to those of other planets. Unlike Kepler's first and second laws that describe the motion characteristics of a single planet, the third law makes a comparison between the motion characteristics of different planets. The comparison being made is that the ratio of the squares of the periods to the cubes of their average distances from the sun is the same for every one of the planets.

A sample of vinegar has a hydronium concentration of 1.6 × 10-3 M. What is the pH of the vinegar?

loris [4]

PH is defined as the negative log of Hydronium Ion concentration.

So, in order to find the pH of vinegar, we find the negative log of its hydronium ion concentration.

$pH=-log[ H_{3}O^{+}] \\ \\ 
pH=-log(1.6 * 10^{-3}) \\ \\ 
pH=2.8$

So, the pH of given vinegar solution will be 2.8.

Therefore, the answer to this question is option B
