	How to calculate the molar masses of chemical compounds
		Molar masses of common chemical compounds that you might find in the chemistry laboratory can range between 18 grams/mole for compounds like water to hundreds of grams per mole for more complex chemical compounds.
		The molar mass of elements is found by looking at the atomic mass of the element on the periodic table.
		Molar masses of chemical compounds are equal to the sums of the molar masses of all the atoms in one molecule of that compound.

	Molar Mass (Site not responding. Last check: 2007-10-28)
		Molar mass is defined as the mass per number of moles, e.g.
		molar mass of oxygen (O2) is 32 kg/kmol.
		The SI unit used for molar mass is kg/kmol.

	Molar Mass Conversion Factors Help
		Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbon’s molar mass of 12.011 g/mol.
		The first step in the determination of the molar mass of a molecular compound is to determine the molecular mass of the compound, which is the weighted average mass of the compound’s naturally occurring molecules.
		The first step in the determination of the molar mass of an ionic compound is to determine its formula mass, which is the weighted average of the mass of the naturally occurring formula units of the substance.

	Molar Mass
		In some cases, the highest mass peak in a mass spectrum is not the molecular ion.
		Therefore, to guess the molar mass of a compound we make a list of all the low mass fragment masses and the losses from all the fragments.
		Your parent peak mass is also tested for bad and poor losses to see if it is a good possibility for the molecular ion.

	Permeation and Polymers : Mecadi GmbH : Molar Mass Calculator
		The Molaric mass calculator calculates the molaric mass of compounds as well as the ideal density of gases in g per l (assumed that the compound behaves like an ideal gas).
		To convert permeation rates in units with mol involved to mass related units with Mecadi's Permeation Rate Calculator the density is needed.
		The molar mass of a compound is the sum of the molar masses of the elements multiplied by their stoichiometry coefficients.

	Postnova Analytics- Light scattering
		Static Light Scattering is used for the determination of Molar Mass, Radius of Gyration and the Second Virial coefficient (A2).
		From the relation of molar mass and radius, the so-called conformation plot, additional information about the shape and structure can be extracted.
		Mass Spectroscopy has become very famous in the last decade, but this technique also requires a big investment and does not reach the same upper molar mass range as light scattering does.

	Postnova Analytics - Static Light Scattering
		In Static Light Scattering a beam of polarized light is focused onto a polymer/particle and the scattered light is detected with a photodiode detector.
		In Static Light Scattering the intensity of this scattered light is measured, which is proportional to the molar mass and the concentration of the particles or polymers in solution.
		This means that by using Static Light Scattering the molar mass of a macromolecule can be calculated when the detector constant K’ has been determined and the sample concentration and the intensity of the scattered light is measured.
