To determine the percent strength of the final solution after diluting a 10% solution, follow these steps:
1. Calculate the amount of solute in the initial solution:
- The initial solution is 100 mL of a 10% solution.
- This means that there are \(10\%\) of \(100 \, \text{mL} = 10 \, \text{mL}\) of solute.
2. After dilution, the total volume of the solution becomes \(1000 \, \text{mL}\).
3. To find the percent strength of the final solution, use the formula for percent concentration:
\[
\text{Percent Strength} = \left( \frac{\text{Amount of Solute}}{\text{Total Volume of Solution}} \right) \times 100
\]
4. Substitute the values:
\[
\text{Percent Strength} = \left( \frac{10 \, \text{mL}}{1000 \, \text{mL}} \right) \times 100 = 1\%
\]
Thus, the percent strength of the final solution is **1%**.
