First of all you have to take into account that the solubility of your compound insists a ratio between medium and alcohol to be 49:1. Prepare this solvent.

Then take 75 micro-liters of the stock solution and dilute it to 500 ml in appropriate flask. My calculations are in the file attached.

I hope that I did the right calculations.

Best regards:)
