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.
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
Accordingly, 1 ml = 1/7.5 mg = 0.133 mg
To determine how many 250 mg doses are in a 10 ml vial, you need to know the concentration of the substance in mg/ml. If the concentration is 250 mg/ml, then there would be 10 doses of 250 mg in a 10 ml vial. If the concentration is lower, you would need to divide the total milligrams in the vial by 250 mg to find the number of doses.
2.5 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.
To make 50 ml of a solution with a concentration of 500 mg per 5 ml, you would need to calculate the total amount needed: 50 ml / 5 ml = 10 units of 5 ml that are needed. Since each unit of 5 ml requires 500 mg, you would need 10 units x 500 mg = 5000 mg. To find out how many 250 mg tablets are needed to make 5000 mg, you would divide 5000 mg by 250 mg per tablet, which equals 20 tablets needed.
How many ml of testosterone would equal 75 mg
800mg is how many ml?
That would depend upon the density, because mg is a unit of mass, while ml is a unit of volume.
