Question
A mixture of two compounds, A and B, was separated by extraction. After the compounds were dried, their masses were found to be: 117 mg of compound A and 91 mg of compound B. Both compounds were recrystallized and weighed again. After recrystallization, the mass of compound A was 91 mg and the mass of compound B was 77 mg. Calculate the percent recovery from recrystallization for both compounds.
Answers
% recovery A = (91/117)*100 = ?
% recovery B = (77/91)*100 = ?
% recovery B = (77/91)*100 = ?
