Which process occurs when an electromagnetic signal is converted to sound waves in a speaker

b . 0.351 L.

Explanation:

Hello!

In this case, since diluted solutions are prepared by adding an extra amount of diluent to a stock-concentrated solution, we infer that the number of moles of solute remains the same, therefore we can write:

Thus, solving for the volume of the stock solution, V1, we obtain:

Now, by plugging in the given data we obtain:

Therefore, the answer is b . 0.351 L.
