How do you convert millimolar to milligrams per liter?

Answer 1

To convert milligrams per liter (mg/l) to milligrams, you need a volume of the substance in question, and then you'll just multiply the two together. In "math speak" here, ( mg/liter ) times ( liters ) equal mg. See where we're going? The first unit is a density, which is weight (mass) per unit of volume. If you have a density of a material and you have a stated volume of the material, you can multiply them together to find out how much mass of that substance you have. If you have oxygen, its density is about 1.429 grams/ liter at STP. That converts to 1429 mg/liter. And if you have, say, 10 liters of the oxygen, you'll have 10 liters x 1429 mg/liter = 14,290 mg of oxygen.

Answer 2

it depends on what the molecular weight is of the substance you have in micromoles. For example 1 mol of acetate = 60g or 60000 mg.

there are 1 000 000 micromols in 1 mol. so if you had 200 micromoles per ml, that would be

200 x 60000/100000 = 12 mg

no micromols you have x weight of 1 mol in micrograms/1000000

Answer 3

molar means moles per liter so you dont need to worry about different volumes.

so... number of moles = mass / molecular mass. firstly divide millimolar by 1000 to get into molar. so multiply number of moles by the molecular weight. and that is your answer in grams. multiply by 1000 to get into mg/litre, or parts per million as it is also known

Answer 4

To convert this you need to divide 1mg by the molecular weight of the compound in question. When you do this, the volume is the same, so there is no further adjustment needed.
