Use scoopula to transfer crude acetanilide
DO NOT place unused/extra acetanilide back into its container. Donate it to the next person in line, or dispose in the waste.
** RECORD THE CRUDE MASS

Use this random number generator
Generate your unique ‘crude mass of acetanilide’ between 1.800 - 2.200 g, using the example in the image.
Record your observations of the crude / impure acetanilide...
Record your observations of the crude / impure acetanilide...
Acetanilide will be lost during the recrystallization, even when performed 'perfectly.' Based on the choices you make in this remote lab, you may lose a lot or a little. When you make such a choice, you'll be given a specific amount of product that's lost.
Keep track of your decisions, product loss, and record observations.
Subtract each of these from your crude acetanilide mass provided by your TA.
You will NOT be penalized for this or graded on your results! Make mistakes!
We want you to have a realistic idea of the consequences of these decisions.
