suppose that instead of a 1 m solution, you decided to make up a 0.5 m solution. how many moles of nacl would there be in one liter?
Answer
Answer:
0.5 moles
Explanation:
Step1: Recall molarity formula
$M=\frac{n}{V}$, where $M$ is molarity, $n$ is number of moles, and $V$ is volume in liters.
Step2: Rearrange for moles
$n = M\times V$
Step3: Substitute values
Given $M = 0.5\ M$ and $V=1\ L$, then $n=0.5\ M\times1\ L = 0.5$ moles.
