In this calorimetery experiment state the independent variable, dependent variable, and your control group. Here is rhe procedure of the experiment below: Gather the items to set up your calorimeter (coffee-cup, stir plate and stir bar, Vernier temperature probe, lid for coffee-cup) Pour 50.0 mL of DI water into the coffee-cup calorimeter. You will be preparing 50.0 mL of a 1.0 M solution of sodium nitrate solution. Using the Vernier temperature probe, record the initial temperature of your DI water. Weigh out the mass of sodium nitrate (4.25g) needed for your solution and pour it into the calorimeter. Immediately begin collecting temperature data. Repeat multiple times.
