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 Question 2 Not yet graded / 10...
