Use the balanced equation to find out how many liters of sulfur dioxide are actually produced at STP if 1.5 x 1027 molecules of zinc sulfide are reacted with excess oxygen and the percent yield is 75%. 2 ZnS(s) + 3 O 2 (g) 2 ZnO(s) + 2 SO 2 (g). Percentage Yield and Actual Yield Practice Problems 1. For the balanced equation shown below, if the reaction of 40.8 grams of C6H6O3 produces a 39.0% yield, how many grams of H2O would be produced?

1. Given the following equation:

5) For the balanced equation shown below, if the reaction of 24.4 grams of C2H3Cl produces a 68.0% yield, how many grams of CO2 would be produced? 23.358 4C2H3Cl+11O2=8CO2+6H2O+2Cl2 Theoretical Yield = (352/250). (24.4) = 34.35 moles Actual Yield = 2335.8/100 = 23.358 grams Click here to go back to Percentage Yield (% Yield). C) Starting with 34.5 g of NH 3, and you isolate 76.4 g of Pt(NH 3) 2 Cl 2, what is the percent yield? Theoretical yield = 303.9 g Pt(NH 3) 2 Cl 2; 25.14% yield. Given the following equation: H 3 PO 4 + 3 KOH g K 3 PO 4 + 3 H 2 O. If 49.0 g of H 3 PO 4 is reacted with excess KOH, determine the percent yield of K 3 PO 4 if you isolate 49.0 g. A 10.50 gram sample of a compound is decomposed to yield 2.40 g Na, 2.37 g S, and 4.73 g O. What is the mass percentage of each element in this compound? 18.2 g Calculate the mass of beryllium (Be) needed to completely react with 18.9 g nitrogen gas (N2) to produce Be3N2, which is the only product of the reaction.

a) Balance the equation.

_____ K₂PtCl₄ + __2___ NH₃g _____ Pt(NH₃)₂Cl₂ + __2___ KCl

b) Determine the theoretical yield of KCl if you start with 34.5 grams of NH₃. 151 g KCl

c) Starting with 34.5 g of NH₃, and you isolate 76.4 g of Pt(NH₃)₂Cl₂, what is the percent yield? Theoretical yield = 303.9 g Pt(NH₃)₂Cl₂; 25.14 % yield

2. Given the following equation:

H₃PO₄ + 3 KOH g K₃PO₄ + 3 H₂O

If 49.0 g of H₃PO₄ is reacted with excess KOH, determine the percent yield of K₃PO₄ if you isolate 49.0 g of K₃PO₄. Theoretical yield = 106.1 g K₃PO₄; 46.17 % yield

3. Given the following equation:

Percent Yield Skill Practice 34 Class

Al₂(SO₃)₃ + 6 NaOH g 3 Na₂SO₃ + 2 Al(OH)₃

Percent Yield Skill Practice 34 Plus

If you start with 389.4 g of Al₂(SO₃)₃ and you isolate 212.4 g of Na₂SO₃, what is your percent yield for this reaction? Theoretical yield = 500.6 g Na₂SO₃; 42.43 % yield

4. Given the following equation:

Al(OH)₃ (s) + 3 HCl (aq) g AlCl₃ (aq) + 3 H₂O (l)

If you start with 50.3 g of Al(OH)₃ and you isolate 39.5 g of AlCl₃, what is the percent yield? Theoretical yield = 86.0 g AlCl₃; 45.93 % yield
