what is the molarity of a solution containing 5.0 moles of kcl in 2.0 l of solution?\na) 2.0 m\nb) 1.0 m\nc) 2.5 m\nd) 10. m\ne) 5.0 m
Answer
Explanation:
Step1: Recall molarity formula
Molarity (M) = $\frac{n}{V}$, where $n$ is the number of moles and $V$ is the volume of the solution in liters.
Step2: Substitute given values
Given $n = 5.0$ moles and $V=2.0$ L. So, $M=\frac{5.0}{2.0}$.
Step3: Calculate molarity
$M = 2.5$ M
Answer:
C. 2.5 M
