what is the molarity of a solution made by dissolving 2.25 mol koh in enough water to make 8.0 l of solution?\n? $\frac{mol}{l}$
Answer
Explanation:
Step1: Recall molarity formula
Molarity (M) = $\frac{n}{V}$, where $n$ is the number of moles of solute and $V$ is the volume of the solution in liters.
Step2: Identify given values
$n = 2.25$ mol (moles of KOH), $V=8.0$ L (volume of solution).
Step3: Calculate molarity
$M=\frac{2.25\text{ mol}}{8.0\text{ L}} = 0.28125$ mol/L.
Answer:
$0.28$ mol/L (rounded to two - decimal places)
