Percent Yield

Front

What is Percent Yield?

Back

Percent Yield is a measure of the efficiency of a chemical reaction, calculated as the ratio of the actual yield to the theoretical yield, expressed as a percentage.

How do you calculate Percent Yield?

Back

Front

What is the theoretical yield?

Back

Theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, based on stoichiometric calculations.

Front

What is the actual yield?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction, which is often less than the theoretical yield.

What is the molar mass of NaCl?

Back

The molar mass of table salt (NaCl) is 58.443 g/mol.

Front

What are the units for molar mass?

Back

The units for molar mass are grams per mole (g/mol).

Front

What does a percent yield of 100% indicate?

Back

A percent yield of 100% indicates that the actual yield is equal to the theoretical yield, meaning the reaction was perfectly efficient.

Front

What does a percent yield of less than 100% indicate?

Back

A percent yield of less than 100% indicates that the reaction was not completely efficient, and some product was lost or not formed.

Front

What factors can affect percent yield?

Back

Factors that can affect percent yield include incomplete reactions, side reactions, loss of product during recovery, and measurement errors.

Front

How do you determine which reaction has the lowest percent yield?

Back

To determine the lowest percent yield, calculate the percent yield for each reaction using the formula and compare the results.
