To calculate the molarity of the solution, use the formula: Molarity (M) = moles of solute / volume of solution in liters.
First, calculate the moles of KOH: moles = mass / molar mass = 5.6 g / 56 g/mol = 0.1 mol
Next, convert the volume from milliliters to liters: 250 ml = 250/1000 = 0.25 L
Now, plug the values into the formula: Molarity = 0.1 mol / 0.25 L = 0.4 M
So, the molarity of the solution is 0.4 M.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
