Final answer:

The value of p² cannot be determined with the information provided as no direct mathematical relationship between pk₂ and p² is given.

Step-by-step explanation:

The exact value of p² cannot be determined from the given information.The variability of pk₂ between 7 and 10 does not provide any specific quantitative relationship to ascertain the value of p². Generally, pk values relate to the logarithm of a dissociation constant in chemistry, which does not translate directly to finding the value of the square of a number in mathematics. Without additional context or a numerical relationship between pk₂ and p, the value of p² remains indeterminate.

The subject matter provided seems to be a combination of chemistry and mathematics, which includes information about electron subshells and quantum numbers, but it is unrelated to the original question about the value of p² based on pk₂.The exact value of p² is 49.To find the value of p², we need to solve the inequality given in the question. Since pk₂ is between 7 and 10, we can write it as 7 < pk₂ < 10.Since pk, is the negative logarithm of Kw, and Kw is between 10^-13 and 10^-12, pk must be between 12 and 13. Therefore, p² equals 49, which is option a).
