State what is the total mass of the excess reactants

Reference no: EM13190035

Cryolite, Na3AlF6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide.

THe Balanced equation is:

Al2O3(s) +6 NaOH(l) +12 HF(g) ->2 Na3AlF6 +9H2O(g)

If 11.5 kilograms of Al2O3(s), 50.4 kilograms of NaOH(l), and 50.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced?

Which reactants will be in excess?
-Al2O3
-NaOH
-HF

What is the total mass of the excess reactants left over after the reaction is complete?
