23) 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, 5.75 kg of CaF2 is treated with an excess of
H2SO4 and yields 2.85 kg of HF. Calculate the percent yield of HF.
