Answer: 56.2 g of Aluminium is needed to react fully with 100 grams of sulphur.
Step-by-step explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
3 moles of
require = 2 moles of
Thus 3.125 moles of
will require=
of
Mass of
Thus 56.2 g of Aluminium is needed to react fully with 100 grams of sulphur.
