Web2 nov. 2024 · 1 mole of CaF2 has 2 moles of Fluoride. 1 mole of CaF2 has 2 moles of Fluoride.as per this equation: CaF2 => Ca+2 + 2F- Therefore moles of Fluoride present = 2 * moles of CaF2 = 2 * 2.628 = 5.25 moles of Fluoride. Mass of fluorine present = mole of fluorine * molar mass = 5.25 * 19 = 99.87 gm WebIn this video, we're gonna go through the answer to question number 17 from chapter 9.4.
