For the reaction shown, compute the theoretical yield of the product (in grams) Ti(s)+2Fe(g) = TiF2(s)

Question

6.0 g Ti, 6.0g F2

Answer 1

1. Convert 6.0 g Ti to moles. moles = grams/molar mass
2. Convert 6.0 g F2 to moles. Same process.
3a. Using the coefficients in the balanced equation, convert moles Ti to moles of the product.
3b. Same process, convert moles F2 to moles of the product.
3c. I expect the answers to 3a and 3b will not agree which means one of them is wrong. The correct answer in limiting reagent problems is ALWAYS the smaller one and the reagent responsible for producing that result is the limiting reagent.

4. Using the smaller value from 3c above, convert that value to grams. g = moles x molar mass.

Answer 2

thank you so much. I needed a mind referesher ;-)
