Calculating mass from a NMR spectrum

  1. Oct 18, 2011 #1
    I'm trying to calculate the mass of a chemical (DMSO) and from a NMR spectrum of water and DMSO. I have the value of the total area under the spectrum and I have the value of the total area corrosponding to the DMSO peak and the total area corrosponding to water.

    I know that the total area of the spectrum is proportional to the number of protons in the sample and DMSO has a 6 protons per molecular mass of 78.

    I have gone some way to calculating it by saying:

    Mass Fraction= (Area of DMSO/Area of total Spectrum) *Correction factor (This is what is needed to convert to mass but unsure what to multiply it by)

    Any help would be much appreciate!:smile:
