"M" stands for molarity, a concentration in moles per liter. You need the molar mass of the solute to get grams per liter, then you need the volume of the dose give to get grams. The molar mass is 250.3 g/mol, so 250.3 g/L. Now multiply by the liquid dose in milliliters to get milligrams, multiply by 1000 for micrograms. A 1 mL dose is 250.3 mg or 250 300 µg,
