to what volume should you dilute 20 mL of a 10 M H2SO4 solution to obtain a 0.130 M H2SO4 solution?
10
To determine the volume of the diluent needed to obtain the desired concentration, you can use the formula for dilution:
C1V1 = C2V2
Where:
C1 = Initial concentration of the solution (10 M)
V1 = Initial volume of the solution to be diluted (20 mL)
C2 = Final desired concentration (0.130 M)
V2 = Final volume of the diluted solution (unknown)
We can rearrange the equation to solve for V2:
V2 = (C1V1) / C2
Plugging in the values:
V2 = (10 M * 20 mL) / 0.130 M
Now, we can calculate the final volume:
V2 ≈ 1538 mL
Therefore, you should dilute the 20 mL of 10 M H2SO4 solution to approximately 1538 mL to achieve a final concentration of 0.130 M.
