Answer:

0.181 M

Explanation:

Begin by finding the total moles by using the volume and molarity given:

\frac{3.25 mol}{1000 mL} x \frac{25.0 mL}{1} = 0.08125 mol

(Remember molarity is mol/L, which is equal to mol/1000 mL.)

Divide the moles by the volume after dilution:

\frac{0.08125 mol}{450.0 mL} x \frac{1000 mL}{1 L} = \frac{0.181 mol}{L} = 0.181 M

The concentration of the diluted solution is 0.181 M.
