  1. 1. Write and balance the equation.
    2. Convert 8.7g F2 to mols. mols = grams/molar mass.
    3. Using the coefficients in the balanced equation, convert mols F2 to mols of the product.
    4. Convert mols product to grams. g = mols x molar mass. The is the theoretical yield (TE).\
    5. %yield = (actual yield/TE)*100 = ?
    3.9 g is the actual yield.
