What is the final molar concentration of acetone solution, when 1.0 mL of 1M HCl, 2.0 mL of water, and 1.0 mL of iodine solution were added to 1.0 mL of 1 M acetone solution?


To find the final molar concentration of acetone in the solution, we need to consider the total volume of the solution after mixing all the components and the initial concentration of acetone.

### Step-by-Step Solution:

1. **Identify the initial volume and concentration of acetone:**
   - Initial volume of acetone solution = 1.0 mL
   - Initial concentration of acetone solution = 1 M

2. **Calculate the number of moles of acetone initially present:**

\[
\text{Moles of acetone} = \text{Concentration} \times \text{Volume} = 1.0 \, \text{M} \times 1.0 \, \text{mL}
\]

Since 1 mL = 0.001 L,

\[
\text{Moles of acetone} = 1.0 \, \text{M} \times 0.001 \, \text{L} = 0.001 \, \text{mol}
\]

3. **Determine the total volume of the final solution:**

\[
\text{Total volume} = 1.0 \, \text{mL (acetone)} + 1.0 \, \text{mL (HCl)} + 2.0 \, \text{mL (water)} + 1.0 \, \text{mL (iodine solution)}
\]

\[
\text{Total volume} = 5.0 \, \text{mL} = 0.005 \, \text{L}
\]

4. **Calculate the final concentration of acetone:**

The final molar concentration of acetone is the number of moles of acetone divided by the total volume of the solution.

\[
\text{Final concentration of acetone} = \frac{\text{Moles of acetone}}{\text{Total volume of solution}}
\]

\[
\text{Final concentration of acetone} = \frac{0.001 \, \text{mol}}{0.005 \, \text{L}} = 0.2 \, \text{M}
\]

### Conclusion:

The final molar concentration of the acetone solution after mixing is **0.2 M**.
