2023 HESI A2 CHEMISTRY EXAM PREP Q&A1. QUESTION Normal body temperature is considered to be 98.6oF. What is the normal body temperature in degrees Celsius? o 100° C o 37° C o 32° F o 21° C Answer: 37° C To convert between Fahrenheit and Celsius scales, use the formula, [°C] = ([°F] – 32) × 5/9. Inserting 98.6oF for the [oF] term, you get 37oC as the answer. [°C] = (98.6°F – 32) × 5/9 [°C] = (66.6) × 5/9 [°C] = 37 2. 2. QUESTION The mass of a grain of sand is 1.672...
