Question
### Problem Statement

An aqueous solution at 25 °C has a pOH of 13.7. Calculate the pH. Be sure your answer has the correct number of significant digits.

#### Answer Input Section
There is a textbox provided for entering your answer. Below the textbox, there are three buttons:
- A button labeled with an "x" for clearing the textbox.
- A button labeled with a circular arrow for resetting.
- A button labeled with a question mark ("?") for help or hints.

### Explanation

To solve this problem, we need to use the relationship between pH and pOH, which is given by:

\[ pH + pOH = 14.00 \]

Given:
- pOH = 13.7

We can rearrange the equation to solve for pH:

\[ pH = 14.00 - pOH \]

Substitute the provided pOH value:

\[ pH = 14.00 - 13.7 \]

\[ pH = 0.3 \]

So, the pH of the solution is 0.3. Ensure that your answer contains the correct number of significant digits based on the given data.
