That would depend upon the density, because mg is a unit of mass, while ml is a unit of volume.
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Does not convert; one is a measure of weight and mL (milliliters) is a measure of volume.
This cannot be sensibly answered. Milliliters (mL or ml) and liters (L) are measures of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.

Any measure of volume can be a fraction of 250 ml.
if water, 250 Mg = 250 megagrams (i'm not sure that's what you mean) 250 Mg (megagrams) = 250,000,000 ml 250 mg (milligram) = 0.25 ml 250 ug (micrograms) = 0.00025 ml
It looks like the 3.5 ml may be extraneous information. If 1 ml yields 250 mg, then you need 400/250 = 1.6 ml, to get 400 mg.
how many teaspoons in 250 ML dry
Twenty 250 mg tablets are needed to make 50 mL if the concentration is to be 500 mg per 5 mL.

20 tablets are necessary.
