Hydrogen fluoride is used in the manufacture of Freons (which destroy ozone in the stratosphere) and in the production of aluminum metal. It is prepared by the reaction CaF2 + H2SO4 → CaSO4 + 2HF In one process, 6.25 kg of CaF2 is treated with an excess of H2SO4 and yields 2.75 kg of HF. Calculate the percent yield of HF.
