Question

During an experiment, Yolanda weighed out 1.4 g of biphenyl at the beginning of the recrystallization. After gravity filtration and suction filtration, she weighed re solid at 1.36g. After baking in the oven and allowing the solid weighed at 0.96 g. Calculate the percent recovery.

Explanation / Answer

%recovery = weight obtained by actual weight x 100

% recovery = 0.96 / 1.4 x100 = 68.57% recovery
