6.92 grams of chlorine gas are mixed with excess iron. The reaction yields 8.50 grams of iron(iii)chlorine. What is the theoretical yield of iron(iii) chlorine?

Answer 1

Balanced Chemical Reaction: 2Fe (s) + 3Cl₂ (g) → 2FeCl₃ (s)

Convert grams of Cl₂ to grams of FeCl₃ to obtain the theoretical yield.

6.92 g Cl₂ x (1 mol Cl₂ / 70.91 g Cl₂) x (2 mol FeCl₃ / 3 mol Cl₂) x (162.20 g FeCl₃ / 1 mol FeCl₃) = 10.6 g FeCl₃ (rounded to 3 significant figures)
