To do this you also need to know the substance you are working with.
Lets take water as an example:
Lets say we have 100 milliliter of water at 20oC and you want to know how many moles this is.
Water has the molecular structure H2O.
So the molar mass is 1.007947*2 + 15.99943 = 18.015324 g/mol.
The density of water at 20oC is 0.998 g/cm3.
We can convert the volume to grams with the formula:
m = V * P
mass (g) = volume (cm3) * density (g/cm3)
So 100 milliliters of water * 0.998 g/cm3 = 99.8 grams of water.
We can turn this into moles by using the formula:
mm = m / n
molar mass = mass / moles
Which we can rewrite to:
n = m / mm
We know the mass (99.8 g) and the molar mass (18 g/mol).
Filling it in gives: 99.8 / 18 = 5.54 moles
So 100 milliliters of water at 20oC equals 5.54 moles.
This can be applied to most substances.

How do you find molarity with mL?
To find molarity (M) with mL, you need to know the volume in milliliters (mL) of the solution and the amount of solute in moles (mol). Molarity is calculated by dividing the moles of solute by the volume of solution in liters (L). You can convert mL to L by dividing by 1000. The formula for molarity is M = moles of solute / liters of solution.
