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 :)
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 find the number of copper (Cu) atoms in 3.7 x 10^3 millimoles, you can use Avogadro's number, which is 6.022 x 10^23 atoms per mole. First, convert millimoles to moles (3.7 x 10^3 millimoles = 3.7 moles), then multiply by Avogadro's number to get the number of atoms (3.7 moles * 6.022 x 10^23 atoms/mole).
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.
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.
Since both of them are per liter....then all you need to do is a one step conversion of moles into grams using the molar mass...essentially you are going to multiply the mol/L by the molar mass in grams of the given substance...
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.

1 mole = 106 micromoles
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.

So molar means moles per litre. So you have to divide by 1000 and multiply by 0.2. 0.5/1000*0.2 is 0.001 millimoles of glycine in your 0.2 millilitres.
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
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.
Molarity
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
So M is moles per litre. Therefore microM is micromoles per litre. There are 1000 litres in a metre cubed. There are also 1000 micromoles in a millimole. Though these cancel each other out, so micromolar is actually the same as millimoles per metre cubed.
