Question

A chemist dilutes 68.5 ml of 25.0 aqueous silver perchlorate solution until the concentration falls to 19.0 m. What is the final volume of the solution after dilution?

Answer 1

Using the dilution equation M1V1 = M2V2, we find that the final volume of the aqueous silver perchlorate solution after dilution to a concentration of 19.0 m is 90 mL.

Step-by-step explanation:

To find the final volume of the solution after dilution, we use the dilution equation M1V1 = M2V2, where M1 and V1 are the initial molarity and volume of the solution, and M2 and V2 are the final molarity and volume respectively. Given that the initial molarity (M1) is 25.0 m, the initial volume (V1) is 68.5 mL, and the final molarity (M2) is 19.0 m, we can rearrange the equation to solve for V2: (25.0 m)(68.5 mL) = (19.0 m)(V2). Solving for V2, we get V2 = (25.0 m × 68.5 mL) / 19.0 m.

Conducting the calculation, we find: V2 = 90 mL (to two significant figures). Therefore, the final volume of the aqueous solution after dilution is 90 mL.
