Answer:
1148 grams
Explanation:
The balanced chemical reaction of this question is as follows:
2Al + 3Cl2 → 2AlCl3
Based on the equation above;
2 moles of Aluminum react to produce 2 moles of Aluminum chloride (AlCl3)
Therefore, 8.6 moles of aluminum will react to produce: 8.6 × 2/2
= 8.6moles of AlCl3.
Using mole = mass ÷ molar mass, to determine the number of grams.
Molar Mass of AlCl3 = 27 + 35.5(3)
= 27 + 106.5
= 133.5g/mol
Using mole = mass/molar mass
Mass = molar mass × mole
Mass = 133.5 × 8.6
Mass = 1148.1
Mass of AlCl3 = 1148 grams
