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
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
The number of millimoles in a milligram depend on the molecular weight of the substance in question. The molecular weight tells how many grams per mole a substance has, and thus how many millimoles in a milligram.
Millimoles is a unit of measurement for the amount of substance, while millimolar is a unit of concentration expressing the concentration of a solution in terms of millimoles per liter. In other words, millimoles measures the quantity of a substance, whereas millimolar measures the concentration of a substance in a solution.
The number of millimoles of HNO3 present at the start of a titration will depend on the initial concentration and volume of the HNO3 solution. To calculate millimoles, you can multiply the concentration of HNO3 in moles per liter by the volume of the solution in liters.
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.
Divide by 1000.
Simple. Do nothing since they are equivalent.
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 :)
Divide by ten. e.g. 200 mg/L = 20%
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
To convert grams (g) to millimoles per liter (mmol/L) for a substance, you need to know the molar mass of the substance. Then you can use the formula: Concentration in mmol/L = (mass in g) / (molar mass in g/mol) * 1000.
Ppm means milligrams per litre. You do not need to adjust the volume and the milli does not need to be adjusted. All you need to do is divide by the molecular weight of the solute.
To convert milligrams per liter to a percentage, you need to know the density of the substance in the solution. Once you have the density, you can use the formula: Percentage = (mg/L * density)/10,000. For example, if you have a solution of substance X with a density of 1 g/mL and it contains 100 mg/L of X, the percentage of X in the solution would be 0.01%.
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.
To convert milligrams per liter (mg/L) to milligrams per kilogram (mg/kg) for sand, you need to know the density of sand to account for the volume change. Once you have the density, you can multiply the mg/L value by 1000 (since 1 liter of water is approximately 1 kilogram) and divide by the density of sand to get the mg/kg value.
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.
Given that a liter of water does weight about a kilogram, there would be a million milligrams of water per liter, so yes, one milligram per liter does work out to be one part per million (ppm).
