Briefly explain whether the following procedural changes would have caused the calculated number of waters of hydration in a hydrate sample to be too high, too low, or unaffected. (a) A student washed the crucible, but failed to heat it to dryness prior to weighing it at the start of the experiment. (b) A student was anxious to finish the experiment and heated the crucible...

number 2 SYNT 439: Synthesizing Aspirin Post - Laboratory Questions (Use the spaces provided for the answers) 1. (1) A student who was in a hurry to complete this experiment did not completely dry the crystalline product before doing the final weighting. How would this error affect the calculated percent yield of the experiment? The results Hughes weight because the crystal has some moisture. It can be added in to own original product weight. So it results high molecular weight....
