none. mg and ml measure different things. Mg measures weight and ml measures volume. You can ask how many mg is 15ml of milk. In this question you are asking what is the weight (in mg) of 15ml of milk
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.

This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, milligrams is a measure of weight or mass.
150 milligrams
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams and milligrams are measures of weight or mass.
That completely depends on the density of the substance in the 1.2 ml. If the 1.2 ml is empty, then there are no milligrams in it at all.
