Do you mean HF as in hydrofluoric acid. Hf is hafnium.
Write and balance the equation.
Convert g CaF2 to mols. moles = grams/molar mass.
Use the coefficients to convert mols CaF2 to mols HF (not Hf)
Convert mols HF to g. g = mols x molar mass. This is the theoretical yield (T. E.).
%yield = (actual yield/T.E.)*100 = ?
