There can be no equivalence.

A milligram is a measure of mass. A millilitre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a millilitre of air. How many milligrams? Next consider a millilitre of water. How many milligrams?

The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.

Many people believe that there is an exact conversion for pure water: that is not true. It is only an approximation and that has been the case since 1964 when the definition of the litre was changed.

How many 250mg in a 10ml vial?

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.


How many 250 mg tablets are needed to make 50 ml if the concentration is to be 500 mg per 5 ml?

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.


250Mg liquid equals how many milliliter?

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


How many ml are in 250 mg?

That would depend upon the density, because mg is a unit of mass, while ml is a unit of volume.


What is 80 mg PO qid of 250 mg per 5 ml?

The prescription of "80 mg PO qid of 250 mg per 5 ml" means that the patient should take 80 milligrams of the medication by mouth (PO) four times a day (qid). Given the concentration of 250 mg per 5 ml, the patient would need to take 1.6 ml of the solution to achieve the 80 mg dose (since 80 mg is one-third of 250 mg). Therefore, the patient should measure out 1.6 ml and take it four times daily.


How many ml of ampicillin will you administer if the order is 400 mg per dose and the available stock is a vial of powder contituted by 3.5 ml and the result is 250 mg of ampicillin in 1 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 mls are in 250 mg of amoxicillin?

To convert milligrams (mg) of amoxicillin to milliliters (ml), you need to know the concentration of the amoxicillin solution. For example, if you have a concentration of 125 mg/ml, then 250 mg would be 2 ml. Without the specific concentration, you cannot directly convert the mass to volume. Always refer to the medication's labeling or consult a healthcare professional for accurate dosing.


How much is 250 ml in mg?

Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.

250 mg equals how many ml?

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.


How many ML will equal the 250 mg?

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.
