Answer: 69.72 kg of cryolite will be produced.
Explanation:
The balanced chemical equation is:
To calculate the moles, we use the equation:
moles of =
moles of =
moles of =
As 1 mole of reacts with 6 moles of
166 moles of reacts with =
moles of
As 1 mole of reacts with 12 moles of
166 moles of reacts with =
moles of
Thus is the limiting reagent.
As 1 mole of produces = 2 moles of cryolite
166 moles of reacts with =
moles of cryolite
Mass of cryolite =
Thus 69.72 kg of cryolite will be produced.
