This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
You have to give 3 times 5 mg = 15 mg therefore you have to give 3 times 2 ml = 6 ml (15 mg = 6 ml of whatever that bottle contains).
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.
2 mg per 1 ml is more concentrated but that means that you will need a bigger quantity of the 0.2 mg per 1 ml mixture for the same amount of the active ingredient.
It is not possible to answer this without knowing the density of the active ingredient per ml. I.e some drugs may be 1000mg per ml, whereas others could be 2mg per ml. There is no standard "amount per ml" for all liquid medicines etc...

7.5 mL per 75 mg which is 10 mg per mL
To administer 2 g in 150 ml over a specific time period, you need to find the concentration in mg per ml. First, convert 2 g to mg (2000 mg). Then, divide the total amount (2000 mg) by the total volume (150 ml) to find the concentration: 2000 mg / 150 ml = 13.33 mg/ml. This is the concentration you need to administer per minute.
To convert nanograms per milliliter to micrograms per deciliter, you need to divide the value in nanograms per milliliter by 10. For example, if you have 100 ng/mL, you would divide by 10 to get 10 ยตg/dL.
It is supposed to be 50 nanograms per ml in a standard test
0.2 ml
A 20% solution would mean 20 g of the substance in 100 ml of solution. To convert this to mg per ml, you would have 20,000 mg of the substance in 100 ml of solution. Therefore, in a 20% solution, there would be 200 mg per ml.

Promethazine HCl 3.6 mg per 5 ml Codeine Phosphate 9 mg per 5 ml Ephedrine HCl 7.2 mg per 5 ml
0.005 ug/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.
I am a pharmacist. 7.5 mL (1.5 teaspoonfuls) of 50 mg per mL Demerol syrup will contain 75 mg. It is a simply and straightforward calculation, but if it helps, you can think of 50 mg per 5 mL as being 10 mg per mL. Therefore, 7.5 mL of the syrup contains 75 mg.
