Science, Chemistry. 1  Chlorine gas and fluorine gas react to form chlorine trifluoride gas. 2  Initially, 1.75 mol of chlorine and 3.68 mol of fluorine are combined. 3  After the reaction is complete, 192 g of chlorine trifluoride are obtained.l2 + 3F2 = 2ClF3; relevant stoichiometric relationships are: 1 mole, 3 moles, 2 moles = 2Ã92.5 = 185 g. 1.75 moles of chlorine reacts with 3Ã1.75=5.25 moles of fluorine, but in actual practice 3.68 moles of fluorine is present.
