The key reaction (unbalanced) in the manufacture of syn-thetic cryolite for aluminum electrolysis is HF(g)+ Al(OH)₃(s) +NaOH(aq) →Na₃AlF₆(aq) +H₂O(l) Assuming a 95.6% yield of dried, crystallized product, whatmass (in kg) of cryolite can be obtained from the reaction of 365 kg of Al(OH)₃, 1.20 m3of 50.0% by mass aqueous NaOH (d=1.53 g/mL), and 265 m³ of gaseous HF at 305 kPa and 91.5°C? (Assume that the ideal gas law holds.)
