From 5g of benzopinacol you obtained benzopinacolona 75% crude. The yield after recrystallization was 2 grams. benzapinacol molecular weight = 366.46 g / mol benzopinacolone molecular weight = 348.44 g / mol determine: a) grams of benzopinacolona (without recrystallization) obtained raw (crude) b) the% yield of pure product (as recrystallized) please put all the steps
