0.05 M KOH?

To understand what "0.05 M KOH" means, let's break it down:

"M" stands for molarity, which is a unit used to express the concentration of a solution. Molarity represents the number of moles of solute (in this case, KOH) per liter of solution.

In this case, "0.05 M" means that the concentration of KOH in the solution is 0.05 moles per liter.

So, if you have a 1 liter solution of 0.05 M KOH, it would contain 0.05 moles of KOH.

To calculate the amount of KOH in a different volume of solution, you would need to use the equation:

moles of KOH = molarity × volume (in liters)

For example, if you have 0.1 liters of a 0.05 M KOH solution:

moles of KOH = 0.05 M × 0.1 L
= 0.005 moles of KOH

Therefore, in 0.1 liters of a 0.05 M KOH solution, there would be 0.005 moles of KOH.
