If I take 0.50 L of a 0.350 M solution and add water until the total volume is 0

Question

If I take 0.50 L of a 0.350 M solution and add water until the total volume is 0.75 L, what is the concentration (molarity) of the final solution? Select one: 1. 0.26 M 2. 0.13 M 3. 1.1 M 4. 0.52 M 5. 0.23 M If I take 0.50 L of a 0.350 M solution and add water until the total volume is 0.75 L, what is the concentration (molarity) of the final solution?

Explanation / Answer

C1V1 = C2V2 where C is concentration and V is volume

0.50L * .350M = x M * .75L

x = .23 M
