2 M means 2 mol/L. It is a concentration, not an amount, so the answer depends on how much of each of the other concentrations you wish to make. Take any convenitnet amount, and dilute it to a new final volume which is a multiple of what you take 100 mM : 20 X 20 mM : 100 X 1 mM : 2000 X Flag Im trying to convert 1mM to the standard units of m /cm3. The unit of molarity is moles per litre and that 1 litre is 1000cm3, but when im trying to get this into any sence for my work im just hitting a brick wall. Please help. Re: 41mg/ml to 1mM That is quite a specialist question, and you need to give a bit more information. What is the material, and what do you wish to do with it? Are you making the solution up yourself? The ratio of rise to run is the trignometric function known as the tangent. The inverse of this is the arctangent (literally, the arc whose tangent is) The rise and run must be in the same units. 1mm in 285 m is an EXTREMELY small slope, but express it as 0.001 m / 285 m . The arctan is 0.0002° 0.7024 arcseconds. On many calculators the arctan function shows as tan followed by a - 1 superscript.
