Calculate the molecular weight of hydrogen: Hydrogen has a molecular weight of 2.016 g/mol. Convert ppm to a fraction: ppm is a unit of concentration, which means it is expressed as a fraction of the total weight of the substance being measured. To convert ppm to a fraction, divide the number of ppm by 1,000,000. In this case, 100 ppm would be expressed as 0.0001. Calculate the weight of the sample: You will need to know the weight of the sample being measured in grams. Use the following formula to convert ppm to umol/gm:
(ppm/1,000,000) x weight of sample (gm) x 1,000,000 / molecular weight of hydrogen
So, using the values given above:
(100/1,000,000) x weight of sample (gm) x 1,000,000 / 2.016 = umol/gm of hydrogen
For example, if the weight of the sample is 5 grams:
(100/1,000,000) x 5 x 1,000,000 / 2.016 = 247,015 umol/gm of hydrogen
Therefore, the concentration of hydrogen in the sample is 247,015 umol/gm.
