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 moles per liter to millimoles per liter, you simply multiply the concentration in moles per liter by 1000. This is because there are 1000 millimoles in 1 mole. So if you have a concentration of 0.5 moles per liter, the concentration in millimoles per liter would be 500 millimoles per liter.
You simply multiply by 1000. This is because milli means 1/1000, so there are 1000 millimoles in a mole. More to the point, there are 1000 millimolar in 1 molar.
convert to liters, then multiply by density of substance. with the grams, use the
moles=mass/molar mass to find moles
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...
