In order to convert between milligrams and micromoles, one has to know the molar mass of the substance in question, then simply convert from grams to moles. As an example, let's assume that the measurement is that of oxygen, or O2, and that there's 10 milligrams per liter. First, divide by 1,000, to convert to grams, in this case, .01 grams. Then, divide this amount by the molar mass, which represents the number of grams in a mole. For O2, this is approximately 31.9988. This gives us a result of around .0003125 moles, or 3.125 x 10^-4. Then, we multiply by 1,000,000 to convert from moles to micromoles. The end result is approximately 312.5 micromoles in the liter.
You have to divide nanomoles by 1000 to convert to micromoles. From this, you have to multiply by the molecular weight to convert to micrograms. the volume values are the same so this is all you have to do.
1 milligram = 1,000 micrograms -- Take the number of micrograms per liter -- Divide by 1,000 -- The answer is the number of milligrams per liter. Example: 6 micrograms per liter = 0.006 milligrams per liter.
1 microgram = 1 millionth of a gram or .000001 - so, just move the decimal point over to the appropriate position. As long as you don't change the value of the number, you can do what you want to it.
First you need to know the molecular weight of the of the substance. For example 100 uM NaOH (MW 40) = 100/1,000 X 40 = 4 mg/L.
How do you convert Milligrams per liter to moles per liter?
to convert millimoles into micromoles just multipy you're answer by 1000.
divide by 1000 then divide by the molar mass.
First off, you have to multiply by 1000 to convert micro to nanograms. Then you divide by the molecular weight to connect nanograms to nanomoles.
Divide by 1 million. Example: 2.35 moles/liter = 2.35 × 10-6 moles per microliter
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
milligram divided by 1000 will give you grams, now use the molecular weight to get the number of moles. next divide dl by 10 to get liters. now you got moles per liter :) There is another simple way to convert miligram per dl into milimoles: 1gm/dl-multiply by 0.055= mm/litre and reverse mm/L divided by 0.055=mg/dl
Boron is abundantEstimated Crustal Abundance: 1.0×101 milligrams per kilogramEstimated Oceanic Abundance: 4.44 milligrams per liter
moles per liter mol/L
No .1 mol per litre is equal to1000 mol per cubic metre
1 mole = 106 micromoles
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
They are the same thing. You have to divide to convert micrograms to milligrams. You have to multiply to convert per litre to per metre cubed. these cancel out.
divide by the molecular mass, (units of gram per mol)
note: 1 miligrame=0.001gram 1dl(deciliter) = 0.1 liter to convert multiply 1000/10
3.6 (milligrams per deciliter) = 36 milligrams per liter.
Concentration is usually expressed in moles per liter, which is called molarity. You could also use moles per mL and other measures of volume. It is also possible to convert this to any measurement of mass/volume (such as grams per liter, milligrams per liter, etc) Molarity. which is Moles/Liter. molarity is expressed as captial m. (M) so if you have 15 M HCl(aq) it is MUCH more concentrated than 5 M HCl(aq)
Each milligram per liter = 1.0 × 10-9 kilograms per cubic centimeter. So, multiply milligrams per liter by 1.0 x 10-9 to get kg per cubic cm.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
0.461 milligrams per litre
1 milligram per liter = 0.000121703815 troy ounces per US gallon. So, multiply the number of mg per liter by 0.000121703815 to get troy ounces per US gallon. Example, 500 (milligrams per liter) x 0.000121703815 = 0.0608519075 troy ounces per US gallon.
2.5g/100ml = moles/1L First convert the ml into L. 2.5g/.100L = moles/1L Cross multiply. 25 moles/ 1L
