i) What two criteria should you ensure about your melting point sample before you fill the melting point capillary? j) After filling the capillary, what do you do to avoid air pockets? k) You accidentally overshoot the melting point of Z and the sample melts before you get a reading. Why should you not just wait for it to cool down and redo the determination with the same sample?

A student was trying to prepare acetaminophen in the laboratory. She found a melting point range of 169-173. The melting of acetaminophen is reported to be 168-172c. How could the student have verified that the produce is acetaminophen? Retake the sample melting point with more material in the sample. Ask the lab partner to measure the melting point of the sample. Take a mixed melting point with an authentic sample of acetaminophen
A student placed about 1 cm of freshly recrystallized loosely packed solid into a melting-point capillary tube. The student noted that the solid melted 30 degrees lower than expected and the solid seemed to jump/separate in the tube as the temperature increased in the melting point apparatus. When the student measured the melting point the following day with less solid that was more tightly packed, the melting point was at the literature value. Explain what all went wrong with the student's first sample
Heating of the oil bath must done slowly to get a more accurate reading of the melting point of a sample. Why must this be done slowly?
Due to the fact that the liquid you used was a volatile one, it will not completely recondense. Some of the liquid remains in the vapor phase, even at room temperature. If you were able to correct for this by making the vapors recondense completely, would your final molar mass value be greater than, less than or the same as the value you determined? Explain your reasoning.
