To prepare a 20 mM solution of Trolox, first determine the molecular weight of Trolox, which is approximately 250.3 g/mol. Calculate the amount needed by multiplying the desired molarity (20 mM or 0.02 M) by the volume of the solution you wish to prepare (in liters) and the molecular weight. For example, to make 1 liter of a 20 mM solution, dissolve 5.01 grams of Trolox in a suitable solvent, typically distilled water, and then adjust the final volume to 1 liter with the same solvent.
