The devastation in Beirut was caused in part by the large amount of gas formed quickly by the reaction of the explosion. This forms a high pressure area that causes damage as it expands. For simplicity, assume the same exothermic reaction solved for and balanced in the previous question: ammonium nitrate reacting with carbon (solid, graphite) that releases, nitrogen, water and carbon dioxide in the gaseous forms. Use this reaction to answer the following questions. part 1: Based on the balanced chemical reaction, if 2700. metric tons of ammonium nitrate reacted, how many moles of CO2 were released in the explosion? 1.687×107 mol CO2 part 2: Based on the balanced chemical reaction of the explosion of ammonium nitrate, if 2700. tons of ammonium nitrate reacted, what is the total volume of gas released, if the pressure was 1.06 atm and the temperature was 23.5°C? 2.70×109 L part 3: Based on the balanced chemical reaction and your answer in the previous part. What was the work, in kJ, of the system when 2700. tons of ammonium nitrate reacted? (Assume the pressure was 1.06 atm and the temperature was 23.5°C. Be sure to include the correct sign for you submission)

Hello, please help me understand how to solve part 3. much appreciated if you could show work clearly. Here is the entire question with parts 1,2,3. Only need help with question 3.

The devastation in Beirut was caused in part by the large amount of gas formed quickly by the reaction of the explosion. This forms a high pressure area that causes damage as it expands. For simplicity, assume the same exothermic reaction solved for and balanced in the previous question: ammonium nitrate reacting with carbon (solid, graphite) that releases, nitrogen, water and carbon dioxide in the gaseous forms. Use this reaction to answer the following questions.

part 1: Based on the balanced chemical reaction, if 2700. metric tons of ammonium nitrate reacted, how many moles of CO₂ were released in the explosion?

1.687×10⁷ mol CO2

part 2: Based on the balanced chemical reaction of the explosion of ammonium nitrate, if 2700. tons of ammonium nitrate reacted, what is the total volume of gas released, if the pressure was 1.06 atm and the temperature was 23.5°C?

2.70×10⁹ L

part 3: Based on the balanced chemical reaction and your answer in the previous part. What was the work, in kJ, of the system when 2700. tons of ammonium nitrate reacted? (Assume the pressure was 1.06 atm and the temperature was 23.5°C. Be sure to include the correct sign for you submission)
