Measure out 100.0 mL of water into the Styrofoam cup. Place the thermometer into the solution. Allow the temperature reading to stabilize and record the temperature as the “initial temperature.” Be sure to record the mass of the water. Weigh out about 2 grams of solid sodium hydroxide, NaOH, and record the mass to the nearest 0.001 g. ................
