In mass- mass calculations, the molar mass is used to convert mass to moles. The mole ratio 2 mol HF/1 molSnF2 can be used to determine the mass of SnF2 produced according to the equation: Sn (s)+ 2HF (g)= SnF2 (s)+H2 (g) In a volume- volume problem, the L/mol factors always cancel out. Gold is then recovered by reduction with metallic zinc according to the following equation: Z n (s) + 2 [ A u (C N) 2] − (a q) → [ Z n (C N) 4] 2 − (a q) + 2 A u (s). Example Gold is extracted from its ores by treatment with an aqueous cyanide solution, which causes a reaction that forms the soluble [Au (CN) 2] − ion.
