4. While preparing a solution you accidently add more water, increasing the volume of a 0.500 M copper sulfate solution from 100 mL to 150 mL. What is the new concentration of the solution?

Answer 1

Initially, you have 0.500 moles of copper sulfate in 100 mL of solution. This means that the concentration of the solution is 0.500 M.

When you add more water, you increase the volume of the solution to 150 mL. However, you do not add any more copper sulfate. This means that the amount of copper sulfate in the solution remains the same, but the volume of the solution has increased.As a result, the concentration of the solution decreases. The new concentration of the solution can be calculated using the following equation:

new concentration = (initial concentration) * (initial volume) / (new volume)

When we plug in the values, we get:

new concentration = (0.500 M) * (100 mL) / (150 mL)

new concentration = 0.333 M

Therefore, the new concentration of the solution is 0.333 M.
