Answer to Question #160473 in General Chemistry for Brooke Ansems

Question

2 FeCl2 + Cl2 → 2 FeCl3

If 2.4154 moles of FeCl2 are reacted, how many moles of Cl2 will also be reacted?

Answer 1

Solution:

The balanced chemical equation:

2FeCl₂ + Cl₂ → 2FeCl₃

According to the equation above: n(FeCl₂)/2 = n(Cl₂)

Hence,

n(Cl₂) = n(FeCl₂)/2 = 2.4154 mol / 2 = 1.2077 mol

n(Cl₂) = 1.2077 mol

Answer: 1.2077 moles of Cl₂ will also be reacted.
