# Dilution Calculation: What is the Concentration of a Solution?

When it comes to diluting a solution, it's essential to calculate the new concentration accurately. In this case, we are diluting 45 mL of 6.0 M HCl to a final volume of 750 mL. To find the concentration of the solution after dilution, we can use the formula for dilution:

**C1V1 = C2V2**

Where:

**C1** is the initial concentration

**V1** is the initial volume

**C2** is the final concentration (what we are solving for)

**V2** is the final volume

By substituting the given values into the formula and solving for C2, we find that the concentration of the solution after dilution is 0.36 M. This means that the final concentration of the solution is lower than the initial concentration due to the dilution process.
