2Fe + 3Br2 --> 2FeBr3 How many grams of FeBr3 will be produced if 67.0 grams of Br2 react?

Answer 1

We can set-up a three-step stoichiometry problem to solve this:

Step 1: convert 67.0g of Br₂ to moles

Step 2: convert moles of Br₂ to moles of FeBr₃

Step 3: convert moles of FeBr₃ to grams

67.0g Br₂ X (1 mol Br₂ / 159.80g) X (2 mol FeBr₃ / 3 mol Br₂) X (295.55g / 1 mol FeBr₃) = _____gFeBr₃
