Cryolite (Na3AlF6) is used in the commercial production of aluminum from ore. Cryolite itself is produced by the following reaction:

6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2O

A mixture containing 440.0 kg of NaOH, 136.9 kg of Al2O3, and 600.0 kg of HF is heated to 950 °C until it reacts to completion. What is the maximum mass of Na3AlF6 formed?

kg Na3AlF6
