Percent Yield (CHEM 1405)

Back to Chemistry 1405 Practice Problems

$\%yield=\frac{actual}{theoretical}\times100$%

Actual yield is the experimental value              Theoretical yield is the calculated value.

1. When 21.8 g of silver nitrate are reacted with an excess of sodium chloride, 17.8 g of silver chloride are formed. Calculate the percent yield of silver chloride.

           

 

 

 

2. Arsenic is produced by heating arsenic III oxide with carbon. Carbon dioxide is another product.   If 8.87 g of arsenic III oxide is used in the reaction and 5.33 g of arsenic is produced, what is the percent yield? 

 

 

 

 

3. Diiodine pentoxide reacts with carbon monoxide to produce iodine and carbon dioxide. If 2.00 g of carbon monoxide gas is reacted, 3.17 g of iodine is produced.  Calculate the percent yield of the reaction.

 

 

 

 

4. Methanol (CH₃OH) can be produced through the reaction of carbon monoxide and hydrogen gas in the presence of a catalyst. If 75.0 g of carbon monoxide react to produce 68.4 g CH₃OH, what is the percent yield of CH₃OH?
