The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. The molar mass of an element (or compound) is the mass in grams of 1 mole of that substance, a property expressed in units of grams per mole (g/mol)...
A mass spectrometric system is described for the measurement of reactive intermediates in 1 atm flames. The system has been tested on CH4O2 and CH4O2N2 flames and provides for the first time a complete analysis of such flames for species in excess of 105 mole fraction concentration....
