Answer :

A molar empirical mass of 60 g is present ( same as the given molar mass ). Consequently, the molecular formula is CN2OH4.

How is an organic molecule's percent yield calculated?

After dividing the actual yield produced in the lab by the predicted theoretical yield, multiply the result by 100 to determine the yield percentage.

How do you figure out the recovery percentage?

Percent recovery is calculated as the difference between what you actually gathered and what you were expected to collect. Consider that after recrystallization, you obtained 7.0 g of dry pure material from 10.0 g of impure material. Your recovery rate is then 70% (7/10 x 100).
