A student prepared benzil according to the experimental procedure using $2\mathrm{.}58$ g$.$ of benzoin and $12$ mL of nitric acid. The mass of the crude benzil product was $2\mathrm{.}25$ g$.$ and the mass of the recrystallized benzil product was $1\mathrm{.}95$ g$.$ Find the molecular weights for benzoin and benzil, then answer the following questions.

$---$What was the percent yield of the crude benzil? Assume units of $\%.$ Round answer to the first decimal place.

$---$What was the percent yield of the purified benzil? Assume units of $\%.$ Round answer to the first decimal place.

$---$What was the percent recovery of the purified benzil from the crude benzil? Assume units of $\%.$ Round answer to the first decimal place.
