Explanation / Answer

% recovery = (25.3g / 30 g) *100% = 84.3 % It means you recrystallized only 85.3 % of the original 30g(getting 25.3 g) recrystallization is a method to purify synthesized products You dissolve your product in solution; heat it up; let solvenevaporate, and get new purified crystals that precipitate out.
