Explanation:

To find the number of moles in a solution, you can use the formula:

\[ \text{moles} = \text{Molarity} \times \text{Volume (in liters)} \]

In this case, for a 5 M (5 moles per liter) KOH solution with a volume of 1 liter:

\[ \text{moles} = 5 \, \text{M} \times 1 \, \text{L} = 5 \, \text{moles} \]

Therefore, there are 5 moles of KOH in 1 liter of a 5 M KOH solution.
