Question

what is the molar concentration of a solution that contains 5.0 mol hcl in a total volume of 10.0 l? ? (mol/l)

Explanation:

Step1: Recall Molarity Formula

Molarity ($M$) is defined as moles of solute per liter of solution, so the formula is $M = \frac{n}{V}$, where $n$ is moles of solute and $V$ is volume in liters.

Step2: Identify Values

Here, $n = 5.0\ \text{mol}$ (moles of HCl) and $V = 10.0\ \text{L}$ (volume of solution).

Step3: Calculate Molarity

Substitute values into the formula: $M = \frac{5.0\ \text{mol}}{10.0\ \text{L}} = 0.50\ \frac{\text{mol}}{\text{L}}$.

Answer:

$0.50$
