CHEM 121 Final Exam Questions and Answers – Portage Learning. Do the three conversions shown below, showing all work: 
1. 328 K = ? oC 
2. 76oC = ? oF 
3. 135oF = ? K 
Your Answer: 
1 - 328 - 273 = 55 C 
2 - (76x 1.8) + 32 = 168.8 F 
3 - (135 - 32) / 1.8 = 57.2 C + 273 = 330.2 K 
 
1. 328K - 273 = 55 oC K → oC(make smaller) -273 
 
2. 76oC x 1.8 + 32 = 168.8 oF C → o oF (make larger) x 1.8 + 32 
 
3. 135oF - 32 ÷ 1.8 = 57.2 + 273 = 330.2 K oF → oC →K

Title: Organic Synthesis 
Purpose: In this lab, three carbon based organic compounds were synthesized to determine 
their true purity. The experiments were done to learn about how to use these compounds’ melting 
points and infrared spectroscopy to determine their percent yield. 
Procedure: 
Experiment 1: Making Acetylsalicylic Acid (aspirin) 
1. Obtain a flask. 
2. Weigh 2 grams of salicylic acid. 
3. Put the 2 grams of salicylic acid into the flask.

Title: Quantitative and Qualitative Analysis 
Purpose: The purpose of this experiment is to learn how to measure the amount of a substance 
that is present in a chemical compound. A metal carbonate will be analyzed to determine how 
much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a 
hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to 
determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...
