let's say you have a nalgene bottle that you want to explode, and its pressure rating is up to 31.5 atm. you choose dry ice as your explosive.
a. if the bottle has a volume of 750.0 mL, how many grams of dry ice do you need to add to blow it up?
b. there isn't enough hear in the air in the bottle to get the dry ice to sublimate fully. you decide to add room temperature water (22.0 degrees C) to it to provide heat. if the specific heat of water is 4.184 J/(g degrees C) and the heat of sublimation of dry ice is 25.23 kJ/mol, how much water do you need to add to sublimate all the dry ice, making the bottle explode, without the water dropping below 5 degrees C (to avoid freezing)? don't worry about the volume of the water.
i think the answers are 41.1 CO2 and 332 g H2O, but how do i do the actual calculations? thanks
