1 mole = 106 micromoles
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
To convert grams per liter to moles per liter, you need to know the molar mass of the substance in grams per mole. Divide the given mass in grams per liter by the molar mass to get moles per liter. This conversion allows you to express the concentration of a substance in terms of its molecular weight, facilitating comparisons and calculations in chemistry.
Molarity
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.
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
To convert micromolar (µM) to milligrams per liter (mg/L), you need to know the molecular weight of the compound in question. Once you have the molecular weight, you can use the formula: concentration (µM) x molecular weight = concentration (mg/L).
First you divide by 1000 to convert to moles/litre. Then you find the molecular mass (add up atomic masses from the periodic table). Multiply moles per litre by the molecular mass and it is in grams per litre.
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.
Depends. It sounds like a vague question. Say you wanted to know how mLs are in 1mol of pure water @ 25c. 1mol of water is 18g. The density of water is 1g/1ml. So 1mol of water is 18mL. So convert the amount of moles into grams. And times the amount of grams by the density. M x D = mL Or if you want to know how many mLs are in 2mols of 0.5mol/L solution. Which is is 4000mL btw. You would divide the amount in moles by the molarity of the solution. N / C = mL Hope I have been somewhat helpful :)
The formula is no. moles is mass over molecular mass. If you multiply micromole by molecular mass you get micrograms. Then you have to divide by 1000 to convert per litre to per millilitre.
In order to convert a microliter per liter to a mililiter per liter, just divide by 1,000.
The conversion factor from grams per liter (g/l) to moles per liter (mol/l) is the molar mass of the substance in grams per mole.
