How To Calculate Percent Composition From Nmr

How To Calculate Percent Composition From Nmr. For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%. The ratio is multiplied by 100 so as to represent it in terms of percentage.
