Chemistry 20 - Unit 4 - Gravimetric Stoichiometry Name: ___________________________________ 1) If 56.0 grams of iron (III) chloride reacts with 38.8 grams of solid vanadium, what mass of vanadium (V) chloride is theoretically produced? If the percent yield of this reaction is 25.0 %, what is the actual yield of vanadium (V) chloride? 2) If 18.0 mL of 2.50 mol/L cesium sulfide reacts with 42.9 grams of nickel (III) nitride, what mass of cesium nitride is theoretically produced? What is the actual mass of cesium nitride if the percent yield is 45.0 %? 3) The invention of trinitrotoluene, otherwise known as TNT, revolutionized the mining industry. When TNT detonates, it does so according to the following unbalanced chemical equation: C 7 H 5 N 3 O 6(s) → N 2(g) + H 2 O (g) + CO (g) + C (s) If 1.0000 x 10 -1 kilograms of TNT detonates, what mass of solid carbon is theoretically produced? If the percent yield of this reaction is 60.0%, what is the actual yield of solid carbon?
