Question

If you add 50 mL of water to 350 mL of a 0.8M NaCl solution, what is the concentration of the diluted solution? A) 0.1 M B) 0.4 M C) 0.8 M D) 1.0 M

Answer 1

The concentration of the diluted solution is 0.1 M (Option A).

Step-by-step explanation:

To find the concentration of the diluted solution, you can use the dilution formula: C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume. In this case, the initial solution has a concentration of 0.8 M and a volume of 350 mL. After dilution, the total volume becomes 400 mL (350 mL + 50 mL). Plugging in these values into the dilution formula, you can find the final concentration (C2), which is 0.1 M.

Option A is the answer.
