To calculate how much 0.05M HCl solution can be made by diluting 250mL of 10M HCl solution, we can use the formula for dilution:
\( C1V1 = C2V2 \)
Where:
- \( C1 \) = initial concentration of the solution (10M)
- \( V1 \) = volume of the initial solution (250mL)
- \( C2 \) = final concentration of the solution (0.05M)
- \( V2 \) = volume of the final solution to be calculated
By substituting the values into the formula, we get:
\( 10M \times 250mL = 0.05M \times V2 \)
Solving for \( V2 \):
\( 10M \times 250mL = 0.05M \times V2 \)
\( 2500 = 0.05V2 \)
\( V2 = 2500 / 0.05 \)
\( V2 = 50000 mL \)
Therefore, you can make 50000mL (or 500mL) of 0.05M HCl solution by diluting 250mL of 10M HCl solution.
