Question

A student began with a 3.12 g sample that contained their unknown and charcoal. After recrystallization the mass of dried crystals recovered was 2.61 g. What was the percent recovery

Answer 1

The percent recovery would be 83.65%

What is Percent Recovery?

The percent recovery of a recrystallization reaction can be mathematically deduced as:

Percent recovery = recovered amount/amount of original sample x 100%

In this case, the recovered amount = 2.61 g, and the original amount of sample = 3.12. Thus:

Percent recovery = 2.61/3.12 x 100%

                           = 83.65%
