To solve the problem shown in the image, let's analyze it step by step.

### Problem Breakdown:
1. **Molarity (M)** is being calculated. The formula for molarity is given as:
   \[
   M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}
   \]

2. **Given:**
   - Volume of HCl (Hydrochloric acid) = 2 mL
   - Volume of H₂O (Water) = 10 mL

### Steps to Solve:

1. **Determine the Total Volume of the Solution:**
   - Total Volume = Volume of HCl + Volume of H₂O
   - Total Volume = 2 mL + 10 mL = 12 mL
   - Convert the total volume to liters:
     \[
     12 \text{ mL} = 0.012 \text{ L}
     \]

2. **Calculate the Number of Moles of HCl:**
   - Since the problem doesn't provide the molarity or number of moles directly, we can assume this is a conceptual problem, where the molarity could be the focus.
   - For example, if you know the molarity of the HCl solution (which is not given here), you could calculate the moles using:
     \[
     \text{Moles of HCl} = M \times \text{Volume in liters}
     \]
   - However, without knowing the molarity or additional data like the concentration, we can't calculate the exact number of moles here.

3. **Setting Up the Molarity Equation:**
   - To calculate Molarity \( M \):
     \[
     M = \frac{\text{moles of HCl}}{0.012 \text{ L}}
     \]
   - To proceed further, the exact number of moles of HCl is required.

### Conclusion:
Without the exact number of moles of HCl or the concentration of the HCl solution, the molarity can't be precisely calculated. The image suggests setting up the formula but doesn't provide enough data to fully solve for \( M \).

Would you like to provide more details, such as the molarity of HCl or the number of moles, or do you have any additional questions?

### Follow-Up Questions:
1. What is the molarity or concentration of the HCl solution?
2. Is there any additional information about the moles of HCl present?
3. Would you like to understand how to convert volumes from mL to L?
4. Do you want an explanation of how molarity is used in chemical calculations?
5. Would you like to know how to experimentally determine the molarity of a solution?

### Tip:
Always ensure that volumes are converted to liters when calculating molarity, as the formula requires the volume in liters to maintain consistency in units.

Learn how to calculate the molarity (M) of a Hydrochloric acid (HCl) solution using the formula M = moles of solute / volume of solution in liters. This problem involves determining molarity without exact moles or concentration data. Suitable for advanced high school students studying chemistry.
