![**Question: Determining the Molality of Hydrochloric Acid Solution**
This question has multiple parts. Work through all the parts to gain the most points.
**Scenario:**
Hydrochloric acid (HCl) is sold as a concentrated aqueous solution. If the concentration of commercial HCl is 11.5 M (molarity) and its density is 1.18 g/cm³, calculate the following:
**a. Calculate the molality of the solution.**

Here, your task is to determine the molality of the HCl solution using the given concentration (molarity) and density. You will enter your answer in the provided input field and submit it. If needed, you can attempt the question multiple times.
**Explanation:**
Molality is calculated using the formula:
\[ \text{Molality} = \frac{\text{moles of solute}}{\text{kilograms of solvent}} \]
Using the given data:
- Molarity (M) = 11.5 mol/L
- Density = 1.18 g/cm³
You need to convert these values to find the molality, considering the volume and mass of the solution.](https://content.bartleby.com/qna-images/question/61a624e8-9805-4882-bd7c-8b439f9ba0a9/5e2980b2-ec23-4c5c-babc-10f8757dae7c/o8f177v_processed.jpeg)
