Answer
moles of Al 10.8 moles
Explanation
Given:
2Al + 3Cl₂ 2AlCl₃
number of moles of AlCl₃ = 10.8 moles
molar mass of AlCl3 = 133 g/mol
Required: moles of Al
Solution:
Use the stoichiometry to determine the moles of Al
The molar ratio between Al and AlCl3 is 2:2
Therefore the number of moles of Al = 10.8 moles x (2/2) = 10.8 moles
