Hi, I would like to set up an experiment with some plants sprayed with an aqueous solution of 200 μM Methyl Jasmonate with 0.025% Zipper surfactant.

From the Sigma/Merch website I see I can buy 25g, but the specification sheet states that the product is liquid. So I assume I will receive a solution containing 25g of product. Is that so?

It is not specified in how many mL the 25g will be diluted, therefore I don't know the concentration of it. I read that MeJA is usually dissolved in ethanol or methanol, but if I need an aqueous solution, how can I make sure the product is correctly dissolved?

How many liters of 200 μM solution can I get from 25g? I made my calculations but I am not completely sure they are right, therefore I would enjoy a double-check.

Thank you very much for your help.
