WebBy comparing the sum of targeted PFASs and total organofluorine concentrations, a mass balance of known and unknown organofluorine could be calculated. Known organofluorine accounted for <1% in most fluorine-containing AFFFs, and it was confirmed that the foams marketed as fluorine-free did not contain measurable amounts of organofluorine … WebA compound was found to contain 63.1% carbon, 11.92% hydrogen and 24.97 fluorine. It has a molar mass of 258.9 g. Solution (Empirical Formula): Step 1: Assume that the mass of a compound is 100 g. [tex]\text {mass C = 63.1 g} [/tex] [tex]\text {mass H = 11.92 g} [/tex] [tex]\text {mass F = 24.97 g} [/tex]
