Question

To prepare her NaOH solution for titration, Brianna measured 10.0 mL of 6.0 m NaOH solution and poured it into a 250 mL volumetric flask. she then filled the flask to the calibration line with water. What is the new concentration of her NaOH solution?

Answer 1

The new concentration of the NaOH solution is 0.24 M.

Step-by-step explanation:

To find the new concentration of the NaOH solution, we can use the dilution formula:

C1V1 = C2V2

Where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

In this case, the initial concentration is 6.0 M (given) and the initial volume is 10.0 mL. The final volume is 250 mL, so we can substitute these values into the formula and solve for C2:

(6.0 M)(10.0 mL) = C2(250 mL)

60.0 = C2(250)

C2 = 0.24 M
