Molar concentration is the most convenient method of expressing the concentration of a solute in a solution. Molarity is defined as the number of moles of solute dissolved per liter of solution, i.e., M = mol/L. All mole calculations are applied to determine the amount in moles of the solution, for which it is the molar concentration If the MW ( Molecular Weight ) of the protein is 40 KD, then the molar concentration for this protein product is 200 (µg/mL)/ 40 (KD) = 5 µM. From molar concentration to mass concentration: The simple formula is: ( µg/mL ) = ( µM ) * ( MW in KD) , ( ng/mL ) = ( nM ) * ( MW in KD) , ( pg/mL ) = ( pM ) * ( MW in KD) Conversion: mass - moles for proteins. Converting mass (weight concentration) into moles (molar concentration) and vice versa for proteins with known molecular weight In chemistry, molar concentration, or molarity, is defined as moles of solute per total liters of solution.
