The First Several Steps of a Chemistry Lab Experiment Are $- 15 ^ { \circ } \mathrm { F }$

Short Answer

The first several steps of a chemistry lab experiment are listed below. The experiment begins with a compound that is stored at $- 15 ^ { \circ } \mathrm { F }$ .
Step 1. Raise the temperature of the compound $109 ^ { \circ } \mathrm { F }$ .
Step 2. Add sulfur and then raise the temperature $80 ^ { \circ } \mathrm { F }$ .
Step 3. Add 15 milliliters of water, stir and raise the temperature $62 ^ { \circ } \mathrm { F }$ .
What is the resulting temperature of the mixture after Step 3? ________ ${}^∘ \mathrm { F }$
