Use the References to access important values if needed for this question. A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.3163 g sample of azulene (C1₁0Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.061x10³ g of water. During the combustion the temperature increases from 23.18 to 25.79 °C. The heat capacity of water is 4.184 J g-¹°C-1. MindTap - Cenga X References The heat capacity of the calorimeter was determined in a previous experiment to be 797.7 J/°C. Molar Heat of Combustion = Submit Answer Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of azulene based on these data.

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.
