Q2/ choose (two) only A- We want to mark off a thermometer in both Celsius and Fahrenheit temperatures. On the Celsius scale, the lowest temperature mark is at-20 and the highest temperature mark is at 40 °C. What are the equivalent Fahrenheit temperatures? B- To determine the density of acetone, a 55.0 gal (gal=3.785 liter) drum is weighed twice. The drum weighs 100.0 Ib when empty and 462.5 lb when filled with acetone. What is the density of acetone expressed in grams per milliliter? C- Indicate the number of protons, neutrons, and electrons in atom of bromine-79.
