Volume Solute (ml)

To create a 250 mL solution with 14.5% methanol content, you need to add 36.25 mL of methanol.

To calculate the volume of methanol required to make a 14.5% methanol solution, you can use a simple equation.

Firstly, you need to understand that the desired concentration is 14.5%, and the total volume of the solution is 250.0 mL.

By substituting these values into the equation:

(Volume of Methanol / Total Volume) x 100% = Desired Concentration

You will get:

(x / 250 mL) x 100% = 14.5%

Solving the equation:

x = (14.5% x 250 mL) / 100%

After calculation, you will find that x = 36.25 mL

Therefore, adding 36.25 mL of methanol to water will create a 250.0 mL solution with 14.5% methanol content.
