Record observations of the solid below that applies to you:
Pure solid - you washed with hot water during hot filtration
Charcoal-infused - you poked a hole in the filter paper in the hot filtration

What is your final mass recovery in grams (g)?
Start with crude mass
Add up all instances of PRODUCT LOSS given throughout this remote lab
REMOTE LAB ONLY
Mass of recrystallized acetanilide = (crude mass) - (PRODUCT LOSS)
Feel free to try the remote lab again but use the mass recovery from your 'first round' in your report
There are no grade penalties for low recovery!
Calculate the percent recovery:
Calculate the percent recovery:
% Recovery = [(recrystallized mass) / (crude mass)] x 100%
